No, you cannot "refile" your taxes, but you can amend your taxes (a different process).
***
Once you file a return, you cannot "edit" it. It's like sending a letter through the mail - once it's mailed you can't call it back to change it.
However, there is a process to "amend" your return. You can do this after the IRS is finished with the initial e-file processing. You usually know this when they send you a refund (if you deserve one).
The form to amend your return is the 1040X which I don't think is available yet in TurboTax.
Since you have already filed, you will need to amend your return. Please see this TurboTax Help page on how to amend.
Be sure to watch this page from time to time to see when (and how) you can start the process.
