We're also having the same issue. I filed 2017, 2018 & 2019 by mail back in June 2020. I owed for 2017 & 2018 which they cashed immediately, but haven't processed yet. I was owed ~$1500 refund for 2019 which I have yet to see, and have not received either of the two stimulus payments. Now my 2020 e-file is not going through because they haven't processed my 2019 return. I've spent 8+ hours dialing every option on the menu and can't get hold of a human!
