@macuser_22, @GabiU I spent an hour or two looking at forum results and trying different options to e-file the other night, including using -0- as the AGI. I am contributing my experience in this thread because 1) I pulled the AGI as described by TT from IRS.gov and can guarantee I correctly typed the digits into the box on TT and 2) this involves a deceased spouse of a joint filing

This appears to be a TT issue and a bug report needs to be filed to the correct software engineering group.
