If you used refund processing, instead of paying your TurboTax fees by credit card, there is an additional fee for that. If you did not use refund processing, the change in your refund amount was done by the IRS. They will send a letter within 3 weeks if they changed your tax return for any reason. But if they did not change anything, the difference is from your TurboTax fees and the Refunding Processing fee (this fee goes to the 3rd party bank). Next year, pay your TurboTax fees with a credit card and don't use that service - the price of it goes up every year...
How to Reduce TurboTax fees - it is too late for this year, but keep these things in mind for next year.
