Can I prepare someone tax return on my turbo tax account?

No...your "Online" account is only for you (and your spouse if married and filing jointly)

If you try to prepare someone else's on it, you destroy your own tax file, and make it unrecoverable.

1) When using the "Online" software...each person, or married couple when filing jointly, must have their own separate account, and pay any fees due separately.

or

2) Buy and use the "desktop" software, which allow multiple tax files to be prepared and filed (only 5 can be e-filed).  The desktop software requires a full MAC or Windows computer....and state efiling costs $20-$25 (except NY)
