@AliciaP1 , that's not what Mike9241 said. The information provided by Mike9241 describes what is necessary for the more-than-2% S-corp shareholder to be able to claim the self-employed health insurance deduction.
In this case, you claim the deduction during the entry of the Schedule K-1 (Form 1120-S) where you mark the box that indicates that you personally paid health insurance premiums and the S-corp paid you wages. TurboTax will then ask for the amount and include it on Schedule 1.
