I did some research because I too was wondering this. I found that it is possible to e-file your MN property tax/CRP. My case may be different from yours, but I feel compelled to give accurate info about this topic.
I am a renter and in the past I have always been required to mail in my CRP and M1PR. TurboTax always clearly informed me of this in prior years. This year my property tax return was e-filed and if you weren't informed to mail it in, you likely e-filed as well.
The best way to determine this is by checking your return. You can determine if your property tax refund was included in your state refund by checking Line 22 of form M1 and then working backwards to form M1RENT which includes information about your property tax refund on Line 13. I had no form M1PR this year.
TurboTax's robot had this response, which is accurate:
The M1PR (Renter's Property Tax Refund return) is a form previously used in Minnesota for renter's property tax refunds. For 2025, you no longer need to mail the M1PR separately because the renter's property tax credit is now claimed directly on the Minnesota Individual Income Tax return (Form M1).
