On the state page titled Medical Care Insurance, it says to "Enter any amount deducted from your monthly Social Security Benefit for ... Parts B and D". In which field?

It's for the state of Wisconsin. Yes, "Medical Care Insurance" is the heading at the top of the screen. I have since completed the page, entering Medicare part B and D in the third available space. I then completed my tax returns, and the amount correctly was added to space 6 on the Wisconsin tax return. This conforms with the Wisconsin State Tax website recommendation, which I found on the official state website.

I am still confused.  Are medicare premium payments (B) deducted from social security deductible in Wisconsin and if so where do retirees put this amount .  I only see worksheets for people who are employed and in the walk through section of Turbo tax I see no place to put these premiums.
