Thank you for your prompt response. I will follow your advice and send a check to the IRS for the $1500 overpayment for the advance child tax credit, but I also don't want to receive the additional $1500 that the IRS is including in the refund amount that's showing in my current Turbotax results. I haven't filed this return yet so I was hoping to eliminate the $1500 from the current refund amount by putting "0" on line C! in the Smart Worksheet of Schedule 8812, instead of "1." When I tried this out, Turbotax automatically lowered my refund by the $1500 amount I was hoping, but the number "0" won't match with the number ("1") shown in box 2 of letter 6419 from the IRS. Will that cause a problem or is this a good way of keeping the $1500 (for the 2nd half of the child tax credit) out of my refund? Also, will any of this activity interfere with my ex-wife's ability to claim the entire $3,000 on her 2021 return? Thanks so much.
