Yes, you do. Form M1PR is filed separately
from your Minnesota State Tax Return and needs to be mailed in.
You can use the TurboTax program to prepare your form and send it in on paper, or you can prepare it online and either mail it or file it online using the Minnesota Department of Revenue portal.
Please see the TurboTax FAQ Can I file my “M1PR (Minnesota Property Tax Refund) through TurboTax?” below for more information and instruction.
