The steps in the TurboTax FAQ below may help you fix your rejected return.
Note: If you get the same rejection a second time (or third, or fourth, or fifth...) and you see no mistakes on your return, select the file by mail option to paper-file your return. Sometimes, returns keep getting rejected even though there's nothing wrong with them (data mismatches, dependents already claimed, and so forth).
In these cases, we recommend paper-filing by mail rather than wasting additional time trying to "fix" something that is beyond your control.
