Help! I can't figure out what I need to do to get the credit flowing to the return.  I have a heat pump. Section B Line21a & b checked Yes, section c entered the address, and entered the cost $11,040 as the cost in the smart worksheet.  The cost is flowing to 29a and I'm getting the $2K on 29e and 30. But the amt form 1040 line 18 is not showing up in the worksheet so it's not allowing any credit.  What do I need to do to get their total taxes to show up? They have taxes of $20K so plenty of room to take the credit. Other than overriding item A for the total amount of taxes, any advice how to get this to calculate?
