Where to enter Last Year's AGI on Turbo Tax rejected amended return?

Hi -

Related to PIN number issues, I have had my amended return rejected. I corrected those, but it was rejected again, because the "last year's AGI" number somehow went from the correct amount to zero. I would like to try again. But when I go through the file windows, , there is no longer an option to change the last year's AGI number... it simply appears as zero with no option to change.

 

How can I amend the last year's AGI in Turbo Tax. Again, I know what the number is, I just can't find a place to put it.
