Where to capture energy credit (max $600?) for upgrade of electric panel to 200 amps

Following question  is where on Form 5695 to record cost for a specific  energy credit, electric  service upgrade to 200A. - 

In Dec 2023  I had my house electric panel service upgraded to 200A in anticipation of a heat pump install completed in February 2024.  On the form or dialog, where do I enter the cost for the electric upgrade? I thought credit for this work is limited to $600 but I may be incorrect. I used the field for heat pump installation cost  but I think this may be incorrect.
