I just need to know how many returns I can file at own time on the app or would it be better for me to have someone else file them for me?

You can also use the online app to prepare multiple returns, but each return requires its own unique login and must be paid for separately (if the return doesn't qualify for Free Edition). Therefore, you can file multiple returns at the same time using the mobile app. Please view the TurboTax FAQ for more information.
