Deductions & credits

The 1500 on line 28 is the remaining CREDIT.  You are getting that added to your refund or reducing a tax due.  Don't watch the Refund Monitor.  Turbo Tax started out assuming you did not get the full 3,000 so your refund was too high.  Then at the end you entered you already got the 1500 advance it took it off.  The 1500  advance does not show up anywhere on  your tax return.
