tax credit for energy efficient windows

I entered into a contract with a window installation contractor on 12/29/2023 to install energy efficient (energy star) windows on my house, however, the windows won't be installed until March 2024.  Because I entered into the contract in 2023, can I claim the tax credit on my 2023 tax return, or have to wait until the 2024 return?
