After you file

Sorry but that did not work. I had to enter $0 for both and that worked. It turns out that if the previous year was filed via paper, only a $0 AGI will get past the filing rejection.

 

My complaint is that if TT knows it was a joint return, they should not be asking for both individually but the total. The AGI for a joint return has only one AGI (the total). TT knows this and should display a note when asking this question to avoid the issue.
