After you file

I did not have to enter my previous year AGI and the IRS already accepted my return. The only thing I can think is that TurboTax or my computer saved my self select pin from last year because I didn't enter that either. There was already a pin there. The IRS website, as highlighted above, says you shouldn't need your previous year's AGI or self select pin as an identifier. Maybe because this is a new thing, the system is glitching?
