AZ tax credit for Charity is a non-refundable credit. A non-refundable tax credit is a tax credit that can only reduce your liability to zero. The credit can't be used to increase your tax refund or to create a tax refund

Thanks for the response MayaD!  Has this changed over the last year?  My refund in prior years was always increased with this credit.

In the past, you may have had more taxable income in the state of Arizona that produced tax liability. In this case, you were able to use that non-refundable credit to reduce your tax liability to produce a refund. This year, you may had less/ no AZ income and less/no tax liability and not be able to take advantage of the credit.

As far as I know, the tax credit for charity has always been a non-refundable credit.

Thank You, Dave!

Looking a little closer, TT does not let me get to form 321 with the walk through, but I can pull up the form and fill it out and I get the credit.  Not consistent behavior.

I may have missed it the first time around, but I do see checkbox for QCO now.  Thanks all!
