Each year, when I have successfully filed my Federal and State Turbotax returns, I put copies of the returns and documents in a manila folder, write on the outside the date that I filed, and the Turbotax PIN for myself and my wife. Her PIN is the one I used to try to get my Federal return accepted (because it was asking only for HER AGI). It did NOT work. If I used a Federal PIN in the past, I didn't record it. Never had to use it before, and never had this problem of return rejection, either.
