I want to make changes in my Mn Return before i file it.

Form M1PR (property tax refund) is filed separately from your Minnesota State Tax Return and isn't due until the August 15th. You may file Form M1PR and claim a refund for up to one year after the original due date. If you file later, you won’t receive a refund. If you paid Minnesota estimated taxes: 

• Sign in. Continue your/take me to my return or pick up where I left off  
  
  NOTE: If you already filed, you won't see the above. Instead -  Go to Tax Timeline, then amend (or add a state if you don't want to amend)
  
  Go to Federal Taxes - Deductions and Credits
• Find Estimates and Other Taxes Paid - On Estimates, start/update/revisit
• Start state estimated taxes
