2016 tax credit question for energy efficient furnace & A/C installation - we are supposed to get a $500 credit, but it is not straightforward - how do we enter this?

Turbo tax only gives me a $300 credit when I enter the amount ($7485) on the "energy-efficient building property" line.  I have to enter my info ($7485) on the "Advanced Main air circulating fan used in a natural gas, propane or oil furnace" line ($50) AND again on the next line -"furnaces and hot water boilers powered by natural gas, propane or oil" ($150).  Is it correct I enter that total amount I paid three times?  I have not used this credit before in previous years.  I have checked my old tax copies to be sure. This is not very straightforward.

Technically, you should divide up the total cost ($7485) and figure out what the AC cost, the furnace cost and the fan cost.  However, in almost all cases, it doesn't matter, so you can just enter the full amount (the only numbers that show up on the tax return will be $300, $150, and $50).  You can even just enter $300, $150, and $50 and it should give you the full credit.
