Arizona prior year tax credit exclusion from current year Federal charitable contributions - How to handle in TurboTax?

I made an $800 maximum contribution to a Qualifying Charitable Organization between 1/1/19 and 4/15/19 and applied the credit to my 2018 AZ return.  I made another $800 maximum contribution to a Qualifying Charitable Organization later in 2019 and applied the credit to my 2019 AZ return.

Both amounts are included in 2019 Federal charitable deductions, and must be adjusted to be excluded from 2019 AZ charitable deductions since they were applied instead as AZ credits ($800 in 2018 and $800 in 2019).

Exclusion of the $800 2019 credit works fine in the program; however, step-by-step does not address how to exclude the $800 2018 credit amount from 2019's charitable contributions.

The only place I can find to do that is to override Part 3 of Schedule 321 by manually adding another $800 (2018's) to the question 'Amount of this contribution claimed as an itemized deduction on Federal Schedule A,' for a total of $1,600.  The tax calculations appear to work correctly when I do this but I receive a TurboTax error message that the current-year charitable contribution exclusion can't be larger than the 2019 credit.

I shouldn't have to override the program.  I do not want to file with an error, and I'm not confident the override I made is treated correctly by the program.

How should I make this necessary adjustment in TurboTax?
