I tried all three ways you suggested with the same result. It always comes to that funky screen with the + sign. And by the way those plus signs don't work for the other folders shown. If I click on another folder it shows the files in that folder but they all have the red turbotax check mark in front of them - even though they are not turbotax files.
Since I see the fully functional Explorer options in 2019 but not in 2020 I don't think it is anything I am doing as a user. I think it is a program problem
