Do self employed people have to complete form 2106. Why? Turbo Tax is forcing me to complete it. Shows up as an incomplete requirement in my return.

No, you report your business expenses on Schedule C if you are self-employed.  You can delete that 2106 form out of your return.  Make sure that you enter all of your expenses under the Business tab at the tab, not the Personal tab.

Form 2106 is generated from the Deductions and Credits page under Personal.  You can go through it and change your answers to No, I did not have employee expenses or you can just delete the form using Forms Mode.
