Hate to be a pain, but that question is specific to expenses for:
-Qualified central air conditioners,
-Natural Gas, propane, or oil water heater or water boilers,
-Replacement of panelboards, subpanels, branch circuits, or feeders (IOW, electrical work),
-Home energy audits,
-Heat pumps and heat pump water heaters, biomass stoves and biomass boilers
We did none of those things. However, I followed your instructions and answered yes. TT took me through questions for lines 21a & b. It did not ask me about the address for 21c, but caught it in Smart Check and I entered.
I still believe this is incorrect. You don't have to install any of the items listed above to receive an energy credit for replacing exterior doors and/or windows.
