"On the K-1 under "Outside Expenses" line 1 I entered 0 since all premiums were reported on one of the 1095-A forms.  Line 2 I enter the amount of Medicare wages on the W2 box 5. Then I QuickZoom to the SE HI deduction wksht.  On the wksht the amount of SE HI paid is shown correctly as $13,717.  Form 7206 shows the correct amount.

When I get to the 1040 line 17 SE HI deduction is showing as $31934 (no idea how where that amount comes from)."

That's a lot of data to follow virtually. Did the insurance premium get correctly reported on the W2 and handled specifically as ">2% shareholder medical ins premium" and did that get entered into the W2 worksheet as such?
