The program starts by giving you the full $3000 credit and then when you entered the $1500 you got in advance the refund in the REFUND METER would have simply been reduced by that amount. If you look at the form 1040 line 28 you would have seen the $1500 credit. If you used a different program and you got a different bottom line then you made an entry error in one of them because if you made the exact same entries in both programs then you would have gotten the exact same bottom line.
