First, you'll need to reach out to the dealer/installer to find out the exact breakdown for each of these items. Make sure you get an itemized statement. Assuming that both of these items are eligible for a federal credit, they have different allowable credit amounts, so you need to have the precise figures for the costs.
Once you've done that, look at the Instructions for Form 5695 (2024), just to make sure that the systems you've installed qualify for the credit.
Finally, see the TurboTax Help article How do I add or remove Form 5695? for entry guidance.
