Go back and check all of your entries for your dependents. A child age 6 thru age 17 is eligible for a $3,000 child tax credit in 2021. Especially check their dates of birth, how long they lived in your home (Whole Year) and that they did NOT provide over one-half of their own support.
What you have reported is having a dependent who is age 18 or older who would only be eligible for the Other Dependent credit of $500.
