The child tax credit is $2000 for your qualifying child under 17, and the other dependent credit is $500, and that is a credit for your dependents over 16. Both credits are nonrefundable credits, and you can only receive an amount up to what your taxes are. Would need more info to help you further, such as why you, and not parents are claiming children, age, income, length of time lived with you in 2019, your tax on 1040 line 12B
