Which Residential Energy Credits are you referring to? Solar, wind, geothermal, fuel cell, insulation, windows, doors, HVAC, furnaces, heat pumps, etc.
Solar. So if I understand the wording, it should be 30% of the installation costs. Which is correctly showed by TT as I step through the windows - after clicking continue on the last window (where it says "Good news! you qualify for $6000"), it takes me back to the main "deductions and credits" window - again where "Home Energy Credits" for 2023 still show $0.
