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?
