After you file

I am having the same issue. I e-filed my 2020 taxes with TurboTax, and my form was rejected because the IRS has no record of my paper form 1040 for my 2019 taxes, but they cashed my check. That's when I found out my 2019 taxes weren't recorded. So I re-filed my 2019 taxes. And I just read that we're not supposed to refile because the IRS is so backed up due to lack of employees to process all the paperwork. Arrrgh!  I can't even get anyone on the phone at the IRS. Good luck to both of us with this! I'd like to get the second and third stimulus checks!!
