Do I need to file a MN state tax return separately?

I live and work in AZ.  My company also has a location in MN and I traveled to MN to work for a few days.  I have received a W-2 for MN as well as AZ with the MN W-2 only containing state wages (less than $1500) and state income tax (less than $100).  Do I need to file a separate MN state tax return?
