For identification purposes, you need to enter either last year’s Self-Select PIN or adjusted gross income (AGI).
We don't store your signature ID in your account and it's not on your printouts. Hopefully, you memorized it, wrote it down, or took a screenshot of it. If you forgot last year's signature ID, you'll need to provide your 2019 AGI for verification purposes.
