After you file

Yes, we both got a letter 6475 for $2800 each, so $5600 total.

 

I made a mistake of reporting only $2800 for the EIP in the Recovery Rebate Credit Worksheet, I thought since it is a joint return, only one needs to be reported.

 

So now IRS sent a notice that I owe the extra $2800 along with interest and penalty. When I amend the return to correctly reflect that $5600 was not received, I see a tax refund.

 

If I do not amend the return, the interest and penalties will keep going up?
