I e-filed my taxes this morning and then got more information and I need to cancel my return and start over. How can I do that. I paid my taxes with a credit card

I used a credit card to pay federal but after looking further I entered something wrong and should not have to pay

Once you e-file you must amend your return to correct it. An amended return cannot be e-filed. You must mail it.
