You cannot file multiple returns in one online account. Never start
another return by going back and
overwriting everything in the return you just filed. This will replace
your
info, which means you won't be able to retrieve your return later. If
you wish to use the Online product to file additional returns, you'll
need to create additional accounts:
-
Sign out of TurboTax Online.
-
Select
the TurboTax Online product you want to use for
the second return and proceed.
- On the Create your
account screen, set up a new login for the second return. You can reuse your email
address if you want to receive e-file notifications for the second return. Up to 5 accounts can be
tied to the same email address.
- After you've created the
new account, you can start working on the second return.
Tip: If you're preparing
multiple returns for family members, it's more economical to switch to the
TurboTax CD/Download software, which lets you e-file up to 5 federal returns at
no additional cost.
