There can be a multitude of reasons why an e-filed tax return is rejected. An email is sent to you by TurboTax when the e-filed tax return is either accepted or rejected. The rejection code and reason for rejection is in the email.
If you used the TurboTax online editions there is no e-file charge for either a Federal or State tax return. The online account fees are for the use of the software to assist in completing a tax return.
There are no refunds for tax returns already filed with the online editions.
