When you are completing the MT state portion of the return, you will come to a series of questions asking about itemized deductions. First, the program will ask you if you itemized in 2016 and then you should get the screen below entitled "Montana Itemized Deductions - Schedule III" (see screenshot 1). You will need to click inside this form and scroll down on the Schedule III until you get to line 27 for Political contributions (limited to $100 per taxpayer). You will then need to make the manual entry of the amount next to each taxpayer.
If you don't get the below screens, you may instead get a screen informing you that you need to enter more itemized deductions in the Federal portion of the program before you will reach the threshold to itemize for Montana.
