How to locate 'Less Common Business Situations' in Self-Employed online version?

I've claimed a vehicle in past tax returns and have stopped using that vehicle for office use. Turbo-Tax recommended me to go to 'Less Common Business Section' and fill up details for section 179 to payback part of the depreciation. How can I perform this activity in Turbo-Tax online self-employed version. A step-by-step guide will be highly appreciated. Thank you
