i filed 2019 late (on Dec 23, 2020) and had to snail mail my filings to both Federal and the State. I have since rec'd both the 2019 Fed and State refund. So, though late, it was not contested. i have now just completed my 2020 filings (in June 2021), and was just rejected due to "incorrect 2019 AGI". however, TTax autopopulated the figure, and i have a hardcopy printed confirming the AGI used. AND i have handwritten the PIN number used. why was it rejected, and what to do?
