@myegor How are you trying to import it? You start a new 2022 return, go up to File-New. Then it should look for any 2021 files or you can browse to where it is. If it says invalid file type that sounds like you are trying to open it, not transfer it.
Or try this. 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. Then save it again with a name and place you can find. Go to File - Save As. Then start a new 2022 return and transfer from the 2021 file.
