I just want to verify this because I don't recall ever needing to fill in last year's AGI to file before, but this year I am being told I need this. I am using Turbotax deluxe desktop. There is a number pre-filled in the AGI slot for me, but the software is also telling me not to guess, because it could cause my return to be rejected - should I assume the pre-filled amount is correct, and is there any way I can double check it if not?
