Deductions & credits

Do you see the 3,000 on line  28?  You are getting it as a credit.  But you saw your  refund go down right?  That's because as soon as you entered your  children in My Info......Turbo Tax gave you the FULL 6,000 as a CREDIT. and your refund was too high.   Then at the end you entered you already got 3,000 so it took 3,000 off your refund (or increased your tax due).
