I mailed my m1pr property tax refund on July 28, it’s due on August 15. If they’re behind and don’t process it by the due date. Will I still get my refund?

I had to amend my 2024 return in order to add and print the m1pr. I was able to efile the amended federal, but I had to mail the state and the m1pr. I don’t know if they received either yet or if they’re busy..
