Why are you trying to import the pdf file? You need to Transfer from the .tax2021 file. The pdf only transfers basic info like your name, ssn & AGI. Copy the .tax2021 file to the new computer hard drive.

Here's an idea. Do you still have 2021 installed? Try opening 2021 program and see if you can get your 2021 return to show up in it. Go to FILE - OPEN. And see if that is the right one.
In the 2021 program do a File-Save AS and give it a easy name you can find or search for. And note where it saves it or select where to save it so you can find it again. The file will end in .tax2021. Then close the 2021 program. Then start a new 2022 return and transfer from the 2021 file.
Windows 10 can move files to different spots like to One Drive. Or to Drop Box. Could it be under a different user on your computer?
