As I noted in my original post, the contribution was paid in 2021 but was taken as a tax credit on their AZ 2020 tax return.  This is allowed.  AZ has organizations that qualify for tax credits.  contributions to these organizations can also qualify for a federal deduction.  AZ further allows a credit for contribution paid before the due date of the return, but that contribution is not allowed for a federal deduction until the return for that year is prepared.  So again contribution paid in 2021 but taken as a tax credit for state purposes in 2020 qualifies for a Federal deduction in 2021.  And Yes, I know the amount is then deducted from itemized deductions for AZ.  Lacerte generally has correctly applied this in the past, but I noticed for one of my clients it did not.  If add the contribution to the Federal Schedule A it automatically transfers over to the AZ Sch A, and I do not see a way in the software to reduce the AZ schedule A for this.  Does someone know how to do this correctly?
