I stoped working as an independant Contractor on December 31, 2017 and have no income in 2018 what needs to be entered into the software?

Nothing.  There are no reporting requirements for ending an independent contractor situation. 

When walking through the TurboTax Interview, you will just answer No when asked if you still have income from self-employment.

If you have passed that question and are being prompted to enter Self-Employment Income you can click Add/Edit next Self-Employment under the Wages and Income Summary then click delete next to the independent contractor work.
