What if I don’t know my last year’s AGI?

If you don’t have last year’s AGI but remember the PIN you used to sign your return, you can select to sign using last year’s PIN. If you do not have last year’s tax form or PIN and cannot get it from the software/professional who submitted your return, you will need to request a transcript from the IRS https://www.irs.gov/individuals/get-transcript.
