I talked to a CPA friend and he explained that the solar credit was more than my tax liability for the year so the remaining credit will roll over to next year. It shows up as a credit carryforward to 2023 on line 16 of Form 5695. You can't see the forms until you pay to file. And you need to make sure you remember to claim it on next year's return. So that is why the refund amount for the standard deduction and the itemized deduction was the same.
