the IRS will send a letter 2-4 weeks after the refund is sent.
Given what others are posting on this board, I suspect it will relate to the Recovery Rebate Credit (line 30 of form 1040) or the ADvance child tax credit (line 28 of Form 1040)
if you did not correctly enter what you had already received for these two benefits, line 28 and / or line 30 were inflated, resulting in a refund that was too high.
what is the dollar difference between what you were expecting and what the IRS sent?
