Hmmm I don't know why my question has a "TurboTax Online" tag on it. I am not asking a question about "TurboTax Online". I use CD/downloaded Premier version, I do not use the online tool. I just want to know how to change my Credit Card info on my Intuit Account. When I try to log into Intuit, it makes me choose which product I use. OK, I select Turbo Tax. I get to a login screen. Put in my log in credentials. I end up at a page that looks like Intuit/TT is trying to find out how I would like to do my taxes. There is a shaded column the left side, down the bottom of that there is listed "Intuit Account" and "SignOut". I click on "Intuit Account" and I find a bunch of info about my account that I can change like my name, my address, opt-in/opt-out of various notifications and emails ... but NO billing information.

Are you in account settings? That is where you will find Billing & Shipping Information.

Please refer to the article below for more instructions.

Solved: How to change credit card on file

When I'm in account settings there is no "billing and shipping" option.

How do I update a declined credit card for a TurboTax Advantage order?

Before you begin, have your "declined payment" email handy.

1. Start by looking up your order at our Check Your Order Status page.
2. Enter the info requested on the declined payment email, then select Update.
3. Enter your TurboTax Advantage login info if requested.
4. Now update your billing info. Your order should now be complete.

If you need to confirm or update the credit card information on file with your subscription:

1. Sign in to your TurboTax Advantage account.
2. Once you've signed in, select Billing and shipping info on the left side, then the TurboTax Advantage info radio button.
3. Select Edit to confirm or update your payment, billing, or shipping address.

It is probably too late to change the info for the current 2021 program so you will have to buy it another way.
