Thank You so much!
I have checked the HASHes and Addresses with the blockchair.com (as well as Blockchain Explorer, Blockonomics), balance is not zero, it shows the BTC balance i am expecting. Addresses i sent to the Sender have the BTC balance, transactions are Confirmed and balance is Unspent.
I understand i should recover the balance with Electrum or elsewhere but not familiar with the patterns and method.
Are there any steps to take or procedure to follow (any information to obtain)?
I have tried this:

Apparently, i am missing something.
Thank You.
Does the address with funds start with 1, 3 or bc1?
Depending on the address format you need to choose a different derivation path.
Following this guide, you should choose these options:

I already have a seed

Enter seed

If your seed words are from a bip39 wallet (i.e. not Electrum) you will be shown this window below. Choose the legacy p2pkh option if the addresses in the originating wallet begin with ‘1’, p2sh-segwit if they begin with ‘3’ and native segwit if they begin with ‘bc1’:
