For how many years can the residential solar ITC credit be carried forward? Section 48 says 20 years, other guidance says only until the program is phased out in 2024.

For example if I install solar in 2021 and become eligible for $10000 solar tax credit, but my total tax liability for 2021-2023 is only $3000, will I be able to claim the remaining $7000 credit in future years (past 2023).
