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.

If you have returns to prepare and file for multiple family members, etc. using desktop download software is more cost effective. For 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 file state for free by mail).
