I need to set up a business for sales of Android apps through the Google Play store. Has anyone done this through TurboTax?

The parts in particular I have questions about are:

1. Should I use my name as name of business or the name I adopted? (It hasn’t been legally registered or trademarked though)
2. Which business code to use? Using 541510 (Computer systems design & related services) for now.
3. Which accounting method to use? I think it’s “cash method”, but can’t quite tell.
4. Did I play an “active role”? I think so since I’m the only one in this “business”, but it’s unclear.
