You can choose any edition of TurboTax to prepare all types of tax returns. When you sign in to your Online account simply choose to start your return in the version you feel you need. If you start out with the Standard and then feel you need more guidance, you can upgrade from there.
Just remember if you have started your return in a version such as Premier or Self-Employed it's not possible to "downgrade" to a lower version. You will need to start a new return in a lower version if this is the case.
