In 2019 I filed my 2018 taxes. It was accepted and I received my refund. In 2020 I e-filed my 2019 taxes. after e-filing I realized I made a big error and completed an amended tax form. I printed this out and mailed it to the IRS. It was mailed on 9/15/2020. I have never received my refund of $1,346. Now I am trying to e-file my 2020 taxes and my AGI keeps getting my taxes rejected. What should I do?
