TurboTax does not actually e-file that form with your state return. TurboTax will fill it out, but you will have to print and mail it to the state. I am not sure if you have already filed your state return or not so I will give you guidance on both. If you have already filed, then you will need to get back into just your state return.
You will need to go back to your TurboTax account after you file and choose the option to "Add a state"
This will let you back into your return without actually adding a state
You will go back to the Minnesota return and proceed through the screens until you get to the one described in the article below
Follow the advice laid out in the article below and be careful not to change anything else on your MN state return while you are filling out the M1PR
After you finish with this form, go to the Print Center under Tax Tools and print your MN return - the M1PR will be in the pdf and you can file it as described in the article below
The other option would be to just e-file the form yourself after filing your MN return with TurboTax. MN has a website dedicated to e-filing this form that you can use and the instructions for filling it out are fairly straightforward and shouldn't be a problem.
