I seen a person ask the same question and this link https://ttlc.intuit.com/community/account-updates/help/how-do-i-update-my-turbotax-account-information/01/25927 was given to him but it doesn't mention anything about adding a credit card. Its a basic how to edit account settings and when you go to your intuit account settings, guess what, there's no credit card option to add/edit.
In step two of the File portion I'm given the option to "charge my credit card" but it doesn't give me the ability to enter my credit card information. I'm stuck.
You may have the "Pay from my Refund" option selected.
Here's how to remove refund processing fees and change your payment method before you e-file:
Unfortunately this isn't working.
The steps go like this
1) Select pay with credit card
2) Page asking for you to agree to a processing fee
3) Goes to "Here's your credit card information" page with unfilled in information
It skips an input page and shows you the final "Heres your info page" without ever allowing you to input your info. Right now it seems like Turbo Tax doesn't allow you to input your CC information to pay

I tried using incognito which would do the same thing. Same issue. Seems like there is an issue with Turbo Tax (or Chrome, but that would still be an issue with Turbo Tax). In case anyone else is wondering you can pay via CC outside of Turbo Tax. Select "Pay by Check" which will allow you to efile without a payment. You'll get a 1040 form. From there IRS.gov has some options for paying by CC . It's pretty straight forward but a hassle
