Result: .- Deletion of my wallet from the data concerning the non-transmission of the respective payment, object of my request for help.
.- Removal also of all payments increasing the network commission.
"In the end my balance is correct".
A little bit of history.
In my Bitcoin wallet app I received from a paper wallet a fraction of BTC, generating the already commented address (in which there is no transaction).
Fortunately I keep the paper wallet in which the balance remains unchanged.
That is great news... sounds like it has all worked out

That was a very good idea keeping the paper wallet!
Again thank you very much and for now I think you can close this thread as a result.

P.S. I would like to make a donation.
This is not necessary... I'm always happy to help, but if you feel that you really want to, I have PM'd you my address.
