I am trying to figure a way to subject an S Corp officer's K-1 profit to SE tax on his 1040. 

I thought there would be a line I could enter the profit on the SE form but there isn't.

I originally thought to enter the profit on Sch C, but then the profit would be double reported on the 1040.

Does anyone know a way to get the SE tax applied to the K-1 profit on a 1040?

Thank you.
