I can not find out my AGI from last year. I’ve tried very hard but cannot find it. I filed my taxes before the deadline but just now realized it was rejected. PLEASE HELP

if you did not keep the 5-digit PIN you invented last year for use now
you'll have to file a paper return via US Mail.

Where do I use this PIN number?

You may e-File using either the AGI or the PIN. leave the other field empty.

What return rejected?  Your 2017 or 2018 return?
