I am eligible for the whole child tax credit, but turbo tax didn't add it in to my refund. Why not?

The Child Tax Credit is entered on your federal tax return Form 1040 on Line 28. It is added to your other tax payments, it is not a separate refund. Your Total taxes from Line 24 are subtracted from your Total tax payments on Line 33. If you have an overpayment then that is entered on Line 34 as your federal tax refund.

You can view your Form 1040 at any time using the online editions. Click on Tax Tools on the left side of the online program screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

Did you get any of the Advance Child Tax Credit?   Then only the other half will be on line 28.  Or did you add a new dependent for 2021 or have a baby in 2021?
