How to cancel $69 payment for TurboTax if I didn't end up filing through TurboTax

I was going through the steps to e-file and paid my $69 fee with a credit card.  I did not end not end up filing my taxes using TurboTax and did not see a way to cancel my return and this transaction.  How do I go about cancelling my credit card transaction since I did not file using TurboTax?
