It appears you are attempting to add the amount as a "State/Local Tax Refund" form 1099-G. This rebate amount on a form 1099-Misc needs to be entered in the "Other Common Income" dropdown where you will find the form 1099-Misc topic. This specific rebate is taxable at the federal level.
Then, in the MN state interview you will enter the same amount in the "MN Tax Rebate" box when asked. this will subtract the amount from MN state taxes.
