You say "made more than $2,500". But, that's not enough info. It depends on how much more than $2500 you made.
What is on lines 1z, 18, 19 and 28 of your form 1040?
Line 1z is your earned income.
Line 18 is your tax liability.
Line 19 is your "regular" Child Tax credit. It will not be more than line 18.
Line 28 is your Additional Child Tax Credit (ACTC). It's calculated based on what's on lines 1z and 19. The ACTC is calculated on Schedule 8812 and is basically 15% of your earned income over $2500, but not more than $1700.
