Where to report sale of partial business vehicle converted to 100% personal use in 2017?

I entered this information when filing for 2017.  Do I need to now report that I sold it in 2018?

that should have been done in 2017.   you'll have to amend 2017 and file by mail becuase efiling is close for 2017

I entered the conversion to 100% personal use and all previous depreciation when I filed TurboTax 2017.  Just wasn't sure if I needed to enter it as sold in 2018?
