@Nance59 your "tax liability" is basically what the IRS says you owe them based on your AGI, based on the graduated income tax tables for 2023. The home energy credits are non-refundable, they provide 1:1 tax credit on liability. It's basically impossible to explain to you without you providing specific figures, this is why it's recommended to have a CPA specifically 1:1 consult you, or pay a bit extra for TT CPA advice. My guess is that your $932 home energy credit (or whatever the amount you said was) is how much tax liability you had leftover so once it brings you to $0 fed tax owed then your credit is done.
I'll let others (.....or your CPA) explain if there's carry-forward leftover for you.
