The state of Michigan Sent me a letter saying I have a past due debut of 1,434.90 It became past due on 4\18\2017. Why did I get this letter. I don't remember missing any payments to my state. Is there a way I can prove I paid? If so what form to I send to the State of Michigan. I thought turbo tax is surrposed to help with that. how can I correct this mistake so I don't keep getting letter saying I owe money.
