Do I heve to complete one state before I can work on another persons return.

You appear to be using online TurboTax.  Is that correct?  That's what is indicated next to your screen name above.

If so, you have to use a different account to prepare an additional online Federal return for someone else.

You cannot prepare a second Federal return in the same online account.   That's a no-no!  That will overwrite the first person's return.

Each online account can only handle 1 Federal return per tax year.

A separate account (separate User ID) is necessary for each Online return, and a separate fee (if applicable).   You can use the same email address in the Account Settings (Profile and Security tabs), if desired for notification purposes, but each User ID must be unique.  A User ID does not have to be an email address.

For future reference, the desktop products (CD/download) can handle multiple returns.
