Going to reply to all comments yes I'm positive my transcripts clearly show my EIP deposit at 3500.00 my bank statements are the exact same 3500.00. My letter is 8400.00 full amount. I also did not receive my full portion of ctc either from July - Dec but that letter was correct. I called the IRS and the rep told me one of two things will happen 1. The IRS will pay my refund but deduct the missing stimulus and i will then have to respond to the letter they issue with MY documents proving the amount i received and their error. or 2. The IRS will investigate further and see the error once they receive my return she said it is possible that ONLY the letter is showing an error amount since my transcripts are showing the actual amount but either way it MUST be paid to me rather it is when my return hits or if i have to send my proof.
