OK, the pop up appears to be the issue. I am using google Chrome. But even when I allow pop ups the problem does not go away. Probably I'd need to close Chrome and restart it, but I am not willing to do that because I have other open tabs were I am working.
So instead I set my default browser to be Edge. Then I tried the import process, had to pick out the motorcycles to prove I am human, and then the import occurred. Then, crucially, I had to "allow" Edge to look for other devices on the network. I would not normally have wanted to do that, the message is terrible. It should say "you must allow this in order for the import to work properly".
Anyway, when I allowed it and then closed the browser window Turbo Tax now shows the imported 1099s from Etrade.
Very poor implementation in my opinion. But I got it to work.
Thanks to all the folks that suggested doing this.
