IRS denies my refund.

The IRS has denied my refund, in fact, they have made a $50000. swing! I found this out by looking for the status of my refund on their site. I am still waiting for their letter.

From the details, they say the problem is related to Child Tax credit "inaccuracy"! They specifically quote schedule 8812 Credits for qualifying children or dependents. I have no qualifying children or dependents, there are no dependents claimed in the return. TT has placed a number on that schedule for Child Tax Credit. The number matches the amount we received in stimulus checks.

In preparation for the discussion with IRS, I wonder if you can tell me where in the interview that number came from, please.
