There is no additional e-filing fee for a federal tax return. However, if you paid a state e-filing fee and were unable to complete your e-filing, please contact TurboTax Customer Support for assistance.
Contact Support during business hours using the info below. NOTE: When entering your question, don't use the word "refund". Instead, use the words "billing issue".
