Definitely contact the state yourself to inquire.  Use the phone number on the letter.  If there is no phone number, then call yourself, by clicking on your state in the link below.

Last but not least, contact your state congressman to request authentication of the letter.  You can't be too safe.

BTW. This wouldn't be the first time the state of Michigan tried every trick in the book to delay refunds, if that's what they're doing.
