I need to amend the additional child tax credit

[DawnC]

That credit is dependent on your earned income and dependents.   Have you already filed your tax return and was it accepted?   Or do you need to edit your dependent info or earned income information?  

The Additional Child Tax Credit can be worth up to $1,700, depending on your income. You must have at least $2,500 in earned income to claim the credit.

The Additional Child Tax Credit  can be claimed when the full Child Tax Credit can’t be used.
