Under the Home Energy Credit section, I put "Yes" under "Did you live in your home with someone else who helped you pay for any energy efficiency improvements, qualified fuel cell property, or home energy audit" since I co-own the home with my partner but it doesn't give me an area to show how the costs were split and when trying to proceed, I get an error message saying "You told us that you lived in your main home with someone else but you didn't enter any costs for what you paid or for what was paid by all occupants of your home".
Does anyone know where I can enter this information to get past the error?
