For an LLC that elected S-corp reporting, self-employed health insurance is not reported on line 13 of the K-1. Rather, since it is taxed as an S-corp, it must follow the tax reporting requirements for that type of entity.
the SEHI should have been on line 7 or 8 of the 1120-S and box 1 of your w-2. it does not show up at all on the K-1 as a separate item

so for the S-corp return the medical insurance should have been included on the same line as your wages
line 7 or 8 (line 7 since you are an officer)
for the w-2 the SEHI should have been included in box 1 (an addition to your wages)
and box 14 with a description like SEHI and the amount
you're going to have to file an amended 1120-s/K-1/ and w-2
otherwise, you're not in compliance with the tax laws and probably not entitled to deduct the SEHI on your 1040 or S-corp
