.Where can I enter pension contributions and medical insurance Ipremiums I paid through my employer who furnishes me a K1 to result in a deuction from my gross income?

Ok ... so you are an owner in an S-corp and you get a W-2 AND a K-1 from the business ...  the 401K contributions should already be on the W-2 box 12 code D and the insurance code DD.  If the insurance is not in box 12 ... then in the K-1 entry section look for these screens  for the HEALTH INSURANCE deduction ...

Or are you a member of a partnership and receive a Schedule K-1 (Form 1065)?

(Since you referred to your "employer," it does seem that, as Critter-3 suggested, you are a shareholder in an S corp rather than a member of a partnership, but I thought I would ask anyway.)
