How do I deduct rent in my mass taxes

[DawnC0]

After you complete your federal taxes, you will start your MA return.  When you go through the MA state interview, TurboTax will ask you about your rent.  You do not enter any rent info under the Federal portion, so it will not be transferred in your MA state return.  

The rent question is near the very end of the state interview.  See the image below to see the screen where your rent is entered.
