Looks like there are two credits.  You might be getting just one of them.

Qualifying resident individuals can claim a refundable child tax credit for tax years 2022 and later. Income restrictions apply in determining eligibility for the credit. The credit is allowed only for eligible children under the age of 6. However, a separate credit may be allowed for children age 16 and younger. For additional information, please see Department publication Income Tax Topics: Family Affordability Tax Credit(opens in new window).
