The tax liability that the credit is allocated to does not include ADDITIONAL taxes like Self-Employment tax or penalty tax on early IRA deductions,
HOWEVER any remaining credit is allocated as the "Additional Child Tax Credit" and reported on your 1040 Line 28 (after the additional tax)
Here is how to preview your 1040 to see how that/those credit(s) was/were applied.
Look at Form 1040 line 19 for the Child Tax Credit
Look at Form 1040 Line 28 for the Additional Child Tax Credit (the amount of the Child Tax Credit that was not used)
