WOW..I did get confused / and waaaaay off track as to whether you were attempting to open a 2020 or 2019 tax file.....(or did you change the text in your question?)

True...you can only read the pages of a 2019 file with the full 2019 software...you can only read the pages of a 2020 file with the full 2020 software

....a newly-installed tax software package does not automatically know a tax file exists already, until you browse to it and open it once.

I moved tons of files for several years taxes , to a a couple of new computers (I've created a lot of test files for different situations)...but I've always had to browse to them and save them once, so that the newly installed tax software keeps track of the file on it's own from that point in time, on. (As long as I don't move the files elsewhere outside of the program's Save functions)
