Moving TT to a Desktop - Problem getting the tax file recognized

I have a new desktop Windows computer and am installing a 2021 version (for the 2021 tax year) of TT.  I want to move my current datafile for 2021 tax year to perform some 2022 what-if calculations before the end of the year.  From the new computer, it always wants to open a new tax return, it can't find any existing returns that I've placed in the appropriate folder.  Basically, it's telling me to "start a new return" or it wants to import from a .2020 tax file.  I don't want to do either of those, I want it to recognize the 2021 files in the folder to continue where I left off.  Not sure what I need to do to make this happen.
