After you file

Please explain and provide some additional details.   We have no idea who "she" is---"she was living at home outside America"---who is "she?"    Your spouse?  Someone else?  

 

So neither you nor "she" were in the U.S. in tax year 2020?  Did you have any U.S. sourced income for tax year 2020?   If you were not in the U.S. in 2020 and had no income from the U.S. in 2020 you have no reason to file a 2020 tax return.
