You could use Online TurboTax since it's done through a browser. The Self-Employed Edition is the same level of product as Home and Business, but the state return is an extra fee, and there is no Forms Mode. Only 1 Federal return can be prepared per online account per year.
Or if you have another computer, such as a Windows PC, you could ask Support to put a Windows version in your download account. (Windows 7 SP1 or later)
