If you have multiple returns to prepare it is much more cost effective to use the desktop download--if you have a full PC or Mac to use it on. With the one-time purchase of the download you can prepare and e-file up to five federal returns and the corresponding state returns ($25 state e-file fee or mail state for free).
Or with online:
When you use online TurboTax software you get one return per fee.
Each return needs its own account and user ID. If you use the same account and user ID for a second return, the second one overwrites the first return and it is lost forever.
