5 digit signature pin

[Breezy241]

I breezed right through my return without writing it down and I need to amend after forgetting to add a form, but is it true that if you use the same account (username) each year, the 5 digit PIN you created for your return (signature) will automatically carry forward to your next year's return as the Prior Year PIN? Last year's AGI carried over to my return as well. I remember the box being automatically filled when I filed. When I go to amend will it be filled in again?

It's not clear how TurboTax will authenticate you when you go to e-File your 2020 amended tax return.

It will probably ask for the AGI amount on your original tax return.

Always print a copy of your completed tax return for your records, and review it carefully before e-Filing.
You will need it if you are audited by the IRS, or to amend if a TurboTax update changes your return or for any other reason,

AND, to find your AGI next year.

OR, this year.
