My computer was hacked and I lost all the files, including my 2019 return. I had to start anew for this year, entering my details and such. This year I want to back up my 2020 to the external back-up just to avoid the same hassle if something like this happens again. Of course I can save the return as a pdf file and back-up it this way but this will not help me to transfer the info from 2020 yo 2021 should I lose the files again. Any suggestions?
