You seem to have left, and I will be, too. In the interest of time, I went ahead and left you info below on how to speak to TurboTax Support for free at the TurboTax Audit Support Center, the department that will help you with IRS letters. They can also question you to see why you are seeing "ready to mail" in your account instead of an efile status. You can also phone the IRS using the phone number on your IRS letter to see if they received your additional info you sent them and the status.
