MI tax preparer needs help with AZ private school credit contribution.  Client (my daughter family return) got transferred to AZ. Is a part-year resident for 2019. She, and spouse, contributed $2,269 to private school. The credit is a maximum of 1,138 for MFJ. They were told to contribute $2,269--why if the credit is a maximum of $1,138? Will the $1,131 amount be a carry over to 2020? If so, I don't see the excess carry over anywhere, except to apply to 2018 ($1,301), or will this be carried to 2020 that can be applied? As you can see, I am completely confused. Thanks in advance, sorry I'm not at all versed in AZ returns.
