Same here. I attempted to dispute the charge with Turbotax and the customer service rep refused. Insisted it was not their charge, that it was an IRS charge. They take no responsibility to notify people when they select the credit card option there will be an additional fee. All they have to do is enter a message and make users click that they read it. It nearly doubled the cost to do my taxes. Infuriating. Last time ever I will use TurboTax.
