Is there a way that with the public key i have from the transaction or the adress that the BTC got sent to to recover something ?
Or at least get find something that could help me.
Not a chance with the current technology,
if that's possible, then re-used bitcoin addresses will be at risk of getting hacked by random people.

The public key cannot be used to recover the private key, unless you have a "no-bullshit" quantum computer.
Much more the address, you have to find a solution to reverse SHA256 and RIPEMD160 in order to get just the public key to get into the next step (previous sentence).

OK lets sum up.

All you have is your public key. It was generated in another software, not Electrum. You never said which one. Do you still have the wallet software that you used to generate the original public key? What happened to it, why can you no longer open or use it?

You thought you had your private key and a seed but as it turns out you have none of that.
When you created the original wallet did it not give you a private key to write down? a seed with 24 words. Did you not write this down anywhere, save it on your PC in a file or somewhere online, on your mobile, etc?

In fact, the key i found is the one that has been used to send to BTC to the "watching only" wallet and it's not a private one like i though.
It seems you are still very confused as to the differences between private keys, public keys and addresses.


A private key... (in WIF format) starts with a "5", "L" or "K" and looks something like:
Code:
5KMUW3epPCabCcJqXsfBBg5c2bnZ4y2a8Qfo6YLrjoS8UfQy3HB
L41NPChv8z7FxEqjDGbVx7VKc4Y4YWHwDhUETTLeXuwuzmpmcDjw
KyioE9wswGdT46bfx2fwcK2rApY9w91rkyzfjtQiy4eZnmWfGNgX


A public key... well that's generally just a string of HEX and looks something like:
Code:
uncompressed 130 HEX chars using [0-9A-F]:
04A627FBEA459A726926F1956898A67EBA5EC47EA53C1FE0D6977077F162D3FA16A6EE7FE9E46554A756110E4506A0334C9A4E5C1C46643654B191B734350A0F8B

or

compressed 66 HEX chars using [0-9A-F]:
03A627FBEA459A726926F1956898A67EBA5EC47EA53C1FE0D6977077F162D3FA16


Public keys can also be encoded as Addresses and begin with "1", "3" or "bc1" and will look something like this:
Code:
18tW1FHLv21JQtdLCpYSpQUSQiqrbE5Vbo
38fxhsGvmuxxWzDMvjdvKLEZ9JgKSMSVGa
bc1qdpav4z3k095hn9ypt7xfsfnjut7gguz2gtf6gx


Which of the above do you have? private key? public key? or address? Huh

The key that i have is a public one (start with bc1....) and this one come's from a wallet i created but I turned the wallet into a "Watching only" one i dont even know how, i know i already said that but i'm clearly a newbie so yeah, my bad.

 The key (public) is a receiving one from the wallet where my money is but reading at your comments, i don't think i'll be able to move these BTC from the wallet since i can't find the seed or pirvate key i had for this wallet.

As you yourself said, you can do nothing if the only thing you have is a public key.
If you don't have the private key of an address, you don't own the funds stored in that. What proves that you are the owner of bitcoins stored in an address is private key. From now on, be more careful. Never deposit to an address which you don't have its private key.

So you mean that you created the wallet on Electrum and then created a new wallet and accidentally put the bc1(Public key) and created it as another wallet(Which is watch-only wallet).

Can you try to check this path if you are using windows.

C:\Users\YourUserName\AppData\Roaming\Electrum\wallets (or %APPDATA%\Electrum\wallets)

For Linux and Mac.

~/.electrum

If it shows multiple files inside that folder Usually "default_wallet" or any name you might be accidentally created another wallet.
You can restore them back by going to restore/new and then browse the wallet file folder and check them one by one and maybe you can find the bc1 address(where you received the BTC) to any wallet file from the wallet folder.
