AZ Form 140: "Gifts Claimed As Credit Too Large"

For federal taxes, I took the Standard Deduction and entered no charitable contributions.

 

For AZ Form 140, for "5C -Total charitable contributions made in 2023 for which you are claiming a

credit under Arizona law for the current (2023) or prior (2022) tax year" - I entered $1100. This was $400 for a QCO, $500 for QFCO, and $200 for the AZ Public School Tax Credit (all maxes for single filer). 
 
TurboTax is telling me "Gifts claimed as credit too large" but offering no other instructions. I had this same issue last year, but changes to live support means they aren't providing me any guidance on how to fix. It this my error or a glitch with TurboTax? Considering trying a different tax filing program if can't figure out a solution, as I'm not confident in TurboTax handling this unique AZ tax credit situation at present and it's the second year in a row I've had issues with very simple returns.
