The copy of your tax return is a PDF file, not a word doc. Most computers or mobile devices can open a pdf file. If you double click on the pdf file it should open in your pdf reader program like Adobe.

If you can't get the side menus to open up to access the prior year..... You need to start entering some basic Personal Info in 2022 for the side menu to open up. Just continue a little ways into 2022. I had to go though about 12 screens.
If you used the Desktop CD/Download program then the only copy is on your computer and not saved or stored online. So you need to make and keep your own backups.
