Filing back taxes

I need to file my 2018 federal and state taxes. I want to do it through tubotax, but I don't know which software to buy and download from their site. I only worked as a contractor so I have 3 1099's. Do I purchase and download the "Premier", "home and business" or "business"? I don't understand why they don't offer a "self-employed" like the current tax year is offering. 

Thanks!
