I paid prior to filing an extension and I was wondering if the payment for TurboTax will be applied when I file later this year.

I think I paid for TurboTax twice last year, once in April and once in October. I filed an extension again this year but I was confused about where the form was located and I paid for TurboTa before I filled out the extension form. I want to make sure I don't pay twice this year. How do I apply the fees I paid for TurboTax now to my order next october?
