The addresses you have (in Electrum), do they start with a '1'? If so, have you checked that you've set the correct derivation path as I mentioned in my previous post?

If you're unsure, go here and tell me how many wallets can you see there (imported addresses don't count): https://login.blockchain.com/en/#/settings/addresses/btc



In the picture above for example, you can see that I have two wallets, so if I wanted to recover the second one (jhlhkj), I would have to use m/44'/0'/1 instead of m/44'/0'/0.


No worries. you're not bothering me.

On the addresses tab, you should have a list with all your addresses:



If you don't have that tab page, go to the "View" menu and select "Show addresses".

If the addresses don't match, then you must've used the wrong derivation path as explained in the 4th step from the guide I gave above.
