there is a reduction of the refundable child tax credit. 8812 dos not match 1040. I think they misplaced 8812. I will resubmitt  form8812 , its worksheet, and letter 6419  to reconcile. If I can not reach the IRS, I will sumbit an 911 form" Request for Taxpayer Advocate Service Assistance.

Thank you all for your replies.
