How to return stuck transaction (instead of pushing it to receiver's addres) ?

[Agbe]

From which client? Based from your other posts, I'll assume that it's Bitcoin Core.
If so, that "stuck transaction" may just be a locally saved transaction and you might have already spent its input.
If not, you can easily abandon it since it must not be in any node's mempool by now.

To "unstuck" it, just go to 'Transactions' tab and use "Right-click->Abandon transaction" and it will be dropped from your wallet.dat.
After abandoning it, the funds that it "locked" should be useable again (the transaction will have red texts).

Of course, I'd advice you to create a backup of your wallet before trying those steps.

I really like the OP question, base on it that bitcoin is a decentralized digital currency and when such has happened, what should be the solution. That not withstanding.
nc50lc, This is what really came to my mind when I read the OP. From where the transaction come and to where the transaction went. That what I was expecting for him to provide the two public keys (the two addresses) the transaction took place. And also based on the decentralized system of the software, I don't think the fund can be reversed because as the transaction didn't go through bad of that time, it would have been reversed automatically but the time frame of the transaction is been long. OP please follow the instructions of nc50lc and others to see if the issue will be solved and if the issue is solved please do well to update this thread and the method used to reverse the fund so others can also learn from you.

So to solve this issue is an interesting challenge.

You have potentially already solved it. If you have imported every private key which has ever held coins from Core in to Electrum, then your Electrum wallet will now contain all the coins you have available to spend. You can forget about the stuck transaction in Core. Electrum does not know about it, and any coins which it would have spent and have not been spent by a different transaction will be available in your Electrum wallet.

1) How do I use "vout" numbers? The are 1 to 3 figures numbers.

Take the first "txid" and paste it in to a block explorer. Then take the first "vout" number and find the corresponding numbered output (the first output is numbered 0, the second output is numbered 1, and so on). Then you can see if that output has been spent in another transaction already.

2) There are a lot of "txid" located below "vin". Do I need all of them?

If you want to check every intput, then yes. Alternatively, if you don't mind the privacy implications of sharing your addresses publicly, you can paste the raw hex of your stuck transaction here and we can take a look for you.

Checking.....
Using blockchain.com explorer.
For some "txid" it works fine and shows info.
But for some of "txid" is says "Oops! We couldn't find what you are looking for."
What does it mean and how should I handle the situation with those non-found "txid" ?

If those are old transactions, they were probably dropped from mempool (not confirmed; double spent and dropped or dropped after a while for low fee).
This means they were never mined, hence they don't exist.

Questions:
1) How do I use "vout" numbers? The are 1 to 3 figures numbers.
2) There are a lot of "txid" located below "vin". Do I need all of them?

As I noted in the instructions, there can be more sets, that's if the transaction is spending more than one input.
You can count the the number of inputs by finding how many txid and vouts sets ("txid" followed by "vout" line) are there before the line ""vout": ["

The "vout" tells which output is the one it's spending.
For example, this transaction: blockchain.com/btc/tx/c41fac476e555483ed6672e99ddcc51ee3ab0028f8ace4d7369c1d0e32ecf948
vout: 0 is bc1pcldgkx2an6fukvssqzkl6tzkll3sj6tcpn6wpxmc99nw8rtkwcws04nvas
vout: 1 is bc1qam5vz2csj0h50qzsnqy3zmunrv0ud6j6m9szd7
If there's a third output, it's vout: 2; for the fourth vout: 3... and so forth.

1. Yes Elecrrum shows transaction history. But it slightly differs from the one in Core.

May be one these reasons:
one is: since Bitcoin Core where the keys are exported is offline, the displayed history isn't correct and what you see in Electrum is the updated/correct balance.
another is: you might have missed some private keys.

For some "txid" it works fine and shows info.
What does it mean and how should I handle the situation with those non-found "txid" ?

Nothing, as I noted in the instructions (again) it's "non-existing, dropped, replaced, etc".
For those that show info, check if the output that is yours is still unspent.

It means that some of the inputs which were being used in your stuck transaction were based on other local transactions which were never broadcast, which is why block explorers can't find them. This might also explain why the stuck transaction was never broadcast, since without the preceding transactions being broadcast the stuck transaction is invalid, as it attempts to spend outputs which do not exist.

In terms of how to handle it - as nc50lc says, do nothing. These outputs never existed in the first place.

This probably also explains why your Electrum transaction history and Core transaction history are different. It sounds like you have more than one locally saved transactions on Core which do not exist on the blockchain.

Guys, here is my report:

All of them are in status "spent".

Except of those that are  "Oops! We couldn't find what you are looking for."

This means that there is no stuck transaction to reverse, is that correct? Please just confirm for me to be 100% sure. As I am only 99 % sure without your confirmation  :-)

Anyway, I don't regret all the work I have done because I have learned a lot.

Btw, is blockchain.com a safe website to visit and click through?
No malware from it?
I became paranoical concerning safety and security :-)

Yes, it means that those inputs are already spent by other transactions.

My best guess is it was spent by your other transactions, you can confirm it by checking all of the outbound transactions' input in Electrum:
Right-click on an outbound transaction, select "View Transaction".
In the advanced transaction details, look for the Inputs (n), the string of numbers/letters is the txid followed by the vin (after the ":")
(see if any of them matched those "spent outputs")

It's a legit site and "probably" wont add a malicious code to their website. (most users do not recommend to use their wallet though)

No malware from it, no, but it is one of the worst blockchain explorers out there. The layout is awful, their timestamps don't make sense, they still report fees per byte which is usually inaccurate, and it lacks any advanced features. Not to mention the company behind it are technically incompetent and host one of the worst wallets in existence.

The two most commonly recommended blockchain explorers on this forum are now https://mempool.space/ and https://blockchair.com/.

OK! The issue is solved then.
I found out (with your help) how the situation with this transaction looks like.

Many thanks  guys for your replies to this post, advices, help!
