I thought paying by credit card would be the same amount as paying through my filing but its $54.99 vs $34.99. Can i cancel CC payment and do it through the filing?

Hi, If you have not already e-filed, you may go back to the beginning of the 'File' section, step through the instructions and you will see how to change your payment method.  If you have already e-filed, then you cannot change your payment method.
