@rjs from what I see in the original post, it starts "working as a contractor for 3 months in 2016". TO me, that's an automatic SCH C minimum, even if only for one day. But like you said, depending on the business expenses, as well as depreciable assets if any,, that will determine the cheapest version that can be used. Personally, I would recommend either Desktop HOme & Business or online Self-Employed if this is the first time dealing with this. The extra help alone will be worth it for that first time.
