Not sure what your question is but since you will have to print, ink sign and mail in the form when using the TT system may I suggest you file this online directly here : https://www.revenue.state.mn.us/filing-property-tax-refund
Classification of Property: Minnesota Property Tax - Attorney Aaron Hall
I live in Minneapolis, MN in Hennepin County. My property tax statement does not provide any codes. For "Class", it just says "Homestead". The MN Property Tax Refund form asks for a CODE; on TurboTax all the codes are listed in the drop down, but it doesn't state what each code means. The State does not provide the codes and their meaning on their sites either. A person has to search all over internet to find. Stumbled across a random Intuit link that provided the codes.
The class rates breakdown can be found on the MN house research site. See the breakdown below:
