I forgot to claim additional child credit. How do I amend it?

[xmasbaby0]

If you are eligible for the additional child tax credit, it was added to your tax return automatically and will be on line 28 of your Form 1040.  

Look at your 2024 Form 1040 to see the child-related credits you received

The Additional Child Tax Credit  can be claimed when the full Child Tax Credit can’t be used.   If you received the full Child Tax Credit, you would not receive any Additional Child Tax Credit.   If you do need to file an amended 2024, return to TurboTax after Feb 13th, when Form 1040-X becomes available.
