When I filed my 2021 federal return with Turbotax, I forgot that I made estimated tax payments during 2021. After I filed, the IRS contacted me and asked me to send in the first two pages of my form 1040 showing the estimated tax payments I made. I also sent a statement from the IRS website proving the estimated tax payments were made.
Today I received Form 3531 along with the two pages of 1040 and the statement I sent to the IRS in April. Box 1 on form 3531 is checked indicating I need to sign my tax return. It's true that I didn't sign the revised 1040 I sent the IRS
Do I sign the 1040 they sent back to me? There are red stamps on form1040 showing when the IRS received and then sent the form back to me. Or do I prepare a new 1040 and sign that?
