Did you possibly add another feature or upgrade your product after you made payment? If you did, the additional charges will be assessed at filing.
If you didn't make any changes, the program may ask you to enter your payment information. If you've already paid you shouldn't be charged again. IF, by chance, you are charged twice, TurboTax will gladly refund your overpayment. See the TurboTax FAQ linked below.
Why was I double-charged or billed twice?
