Credit card items are not the same as Login items - I don’t believe there is an option to auto-fill credit card information unless the user manually initiates the auto-fill. And I think this is the way it should be, because it is possible for a malicious website to spoof a credit card form and capture your credit card info after it fills but before you submit the form.
When I encounter a form requiring credit card information, I just click on the button for the Bitwarden browser extension and then click on the credit card I want from the Tab page - it almost always just pastes everything in. Once in a while, I might have to manually set the expiry date or another field, but that’s rare.
