In 2025, I installed a Heat Pump which qualifies for the tax credit. The overall price I paid included the cost of the Home Energy Audit and the written report was given to me. If I answer "Yes" to the question ("Did you pay for a home energy audit of your main U.S. home and receive a written report from a certified auditor?), what do I enter in the next section for the cost of the audit? I don't have a separate cost for this since it was rolled into the overall cost for the unit. The program won't let me enter $0, so now what?
