After you file

Hello!

The first reply I got was: "If your credit or banking information was on your tax return, and the tax return was rejected, then nothing was sent to the IRS. They do not have your payment. The payment was not made. TurboTax does not make the payment for you or send it separately if it did not go with
your tax return". 

I find this a little hard and disconcerting to believe, since in the agreement you must click on before sending on your form, there is a clause that states Turbotax has it's vendors, (unidentified), handling the charges, and they charge you a fee that is suppose to be separate of what the IRS will charge your credit card.  If you say that your credit card had pending charges on it, it becomes rather obvious that a transaction was attempted on your credit card.  Even if the charges are rejected from the IRS, nothing is said about what the vendors might end up charging you.   The thing that really bother's me, is that TurboTax gives you no assurances of what happens to credit card charges once you e-file, no way of interacting with their credit card vendors, and no return receipts of any transactions, no direct phone number to the IRS office that handles credit card charges.
