I am about to complete, file, and pay for the order, however, I do not see any information about Additional Child Tax Credit or how much will I be getting for my two dependents. Do I need to fill a form for this separately?
Look at your 2019 tax return to see the credits you received:
Child tax credit line 12a
Additional Child Tax Credit line 17b (schedule 8812)
Credit for Other Dependents line 12a
