Yes, I created the wallet on my own. Did a search for how to buy bitcoin and then looked at several wallets. Chose Electrum because it was highly rated. When I opened the download the Electrum 4.3.4 line was at the top along with the 1N8vh... no help from anyone. (I should have done a bit more reading up, it appears.)
I think I can safely say Electrum didn't create that wallet name on it's own, so (somehow) you must have done it. If you can figure out how that happened, that might give you a clue.
I am totally in the dark about private keys. I've seen where they're listed in the pull-down menu but have no idea what to do with them. It just says sweep or export. Is there some kind of connection between them and the 1N8v... label that might give me access to the coin?
You don't just go from private keys in a new (bc1q) Electrum wallet to a legacy ("1") address without manually doing something.
