If you e-filed, I would use the link at your FAQ below in order to verify that your returns were successfully e-filed and accepted:

If they have been accepted, you can use the information from the returns you have saved in order to track your refunds (if any) using the links at the site below:

Lastly, I would check and
see if you might have multiple accounts with TurboTax. Your information may be
safely stored in a secondary account. You can do so by logging out and going
to the recovery website below for a list of user ID's for any email addresses you
may have used.
