How do I figure out what my self-select pin was last year?

[HeatherPLO]

If you don't remember your 5 digit PIN, you do have another option moving forward.

The Self-Select PIN is a random 5-digit number that you enter as your electronic signature when e-filing your return. You can reuse your Self-Select PIN from last year or enter your AGI from last year's tax return. 

For identification purposes, you need to enter either last year’s Self-Select PIN or your AGI. The IRS requires your AGI for identity verification. Please read the TurboTax Help Article listed below, to learn how to locate your AGI.
