You can only do one tax return in each account for the online version. For each new return for another person, you would have to set up a new account and each return would be charged separately.
If you have multiple returns to do, the CD/Desktop version would be much better for you. With that, you can prepare as many returns as you want, and can e-file up to 5 federal returns for free.
The Federal program for Deluxe and above comes with one free state program that can be used as many times as you want. There is an additional fee to e-file every state return but mailing them is free.
