Start by printing your 2022 tax return and look at the Dependents section on the first page. Make sure your child is listed, their social security number is correct, the relationship is correct, and the box for "Child tax credit" is checked.
If so, then whatever credit you qualify for is already included in your refund. If it is less than the full $2000, that is probably because you did not have much income from working. If no box is checked, or the box for "Credit for other dependents" is checked, then we need more information about your situation. Turbotax thinks you don't qualify. If you made a mistake and you should qualify, you can file an amended return to correct the error and obtain the credit.
