I received this answer to the question how do i report the sale of a depreciated car. "Sale of Business Property" Much more info , including a thorough equation.

I will have a taxable gain. 
Is this done on form 4797 ? If yes will it end up on Schedule 1(reported on line 8 of my1040) ? If it does I will have to pay self-employment tax. 
My question is will it effect my self employment tax ?
Thank you
