I am an owner/employee in an S corp, with >2% of shares.

The corp sponsors an insurance plan and pays insurance for me and a portion of the premium for my family. These payments are reported to me on a 1099. I take these as income adjustments on 1040 line 29.

Additional premiums for the company sponsored plan are deducted for dental, vision, and health through payroll deduction. These are included in box 1 of my W-2. Can these premium amounts also go onto 1040 line 29, or must they go to schA? Why?
