I did my son's 2019 taxes and I made a rounding error of $1, well of course he still does not have his 2019 refund. He and his family also did not receive stimulus money because of this. I did his 2020 taxes and tried to efile and it was rejected saying that the 2019 AGI doesn't match what the IRS has. We used Turbo Tax and that is the AGI that was sent, so we really don't know how to make it so he can efile 2020. We really don't want to mail this return since we know it would probably be a year or more before he would get his 2020 refund. Any help would be appreciated.
