OMG, it worked!!!!!
Thank you TT community.
My guess is this - if you printed and mailed your tax returns last year, your AGI did not transfer into the IRS electronic system. The IRS underfunded and overworked and someone likely has to do a manual transfer of that #. Just a guess. I'll see if it works for those returns that I Efiled last year.
TT automatically puts last year's AGI into the box when you are attempting to Efile but they could create an alert that say that if the Efile is unscucessful, delete the entry and enter zero.
