It is asking for my Box 10b - State identification number on my 1099-G. This box is blank, I am in Michigan. Unsure how to proceed as it just tells me to review section.

If you had state taxes withheld from your unemployment, but there is not a state ID number on your form, then use the Federal ID number in box 10b.

If you did not have any state taxes withheld, then leave all the boxes blank (boxes 10a, 10b, and 11).  This includes the dropdown box for the state name.

If anything is entered in box 10a, 10b, or 11, then all of them must be filled in to avoid an error condition causing you to review the entry.
