Deductions & credits
On your 2023 return, when you're in the Deductions and Credits section, click Start or Update next to Home Energy credits. You'll be asked several questions about the property and your expenses.
When you get to the screen asking about a 2022 carryforward, say yes. (This screenshot is from 2024 program, so it references 2023. You first need to do this in 2023 and then carryforward any excess to 2024.)
