Hi, I received same letter from IRS.
Here are those possible reasons listed in the letter:
1. The computation of the credit on Schedule 8812 was incorrect.
2. The amount on Schedule 8812 was not transferred correctly to yourself tax return
3. You received advance child credit payments but did not reconcile them or reconciled them incorrectly.
My submitted 8812 to the IRS showed $3,000 in Child Tax Credit. Joint income is below $150K, We have two children ages 19 and 17 ( under age 17 with qualifying SSNs). We received $250 every month for 6 months. Is the child tax credit payments? I didn't received Letter 6419.
