Thank you. So the online version of TT I am using now has a section for amending last year's return, so I am attempting to do that now. I tell it that I have a form that I need to add to the return, and then that it is a 1099-R. It then asks if I have retirement "income" for 2019, which is the only way to tell it that I need to enter the 1099R. However, once I fill this out, I now have additional federal tax due. This was after tax money I put into the IRA (and subsequent backdoor Roth), so why would doing this amendment result in an additional tax liability?
