How is amount calculated for the child tax credit? I made more than the required 2500 in E.I. The amount of taxes I owe zeroed out but how only $89-CTC and $6-additional

[Vanessa A]

The CTC is limited to your tax liability. The additional child tax credit is calculated by taking subtracting $2,500 from your income and then multiplying that number by 15%.  If you do not have more than $2,500 of eligible income, you would not qualify for the Additional Child Tax Credit.  So if your total income was $3,350 then you would have an additional child tax credit of $127.50

The total per child is $2000.   First the $2000 is used to reduce your tax owed down to zero.  When (if) your tax owed is zero, the "rest" of the $2000 can be added to your refund as the Additional Child Tax Credit----up to a maximum of $1600 per child.  But....that Additional Child Tax Credit also depends on how much you earned by working.  

Take the amount you earned, subtract $2500, and multiply what is left by 15%.  That is your additional child tax credit ---- up to a maximum of $1600 per child.

Look at your 2023 Form 1040 to see the child-related credits you received
