When I filed my refund amount was listed with the third stimulus added. I received my federal refund without the stimulus added. How can I find out why?

The IRS knows if you received the 3rd stimulus amount.   Lots of people have somehow "forgotten" the $1400 per person deposits they received.   If you said that you did not get the $1400 but the IRS records show that you did, then it was removed from your refund.  Check your bank records from mid-March on for deposits made for $1400, and check your online account on the IRS site

If the IRS shows that they sent you a $1400 payment that you did not receive you can have it traced.

If you are missing $1,400 in your refund, you should have received a letter from the IRS telling you that they were adjusting your refund amount and the reason they were doing it.  The IRS  records probably state that you did receive the third stimulus in 2021 when they were being sent out which is why they removed it from your return.

You can go back and check your bank records to see when you received it.  If absolutely did not receive it you can contact the IRS at 800-829-1040
