I've been doing my in-laws' taxes for several years with no problems. When I tried to e-file for 2019, it rejected because it said the amount I entered for 2018 AGI did not match the actual number on the 2018 form. But it is exactly the same. The only thing different from prior years is that my mother-in-law passed away in Jan, 2020, and the error message makes a reference to the spouse. Any thoughts?
