It sounds as you're conflating two entirely different things: 1) Verifying your identity in order to apply for an Apple Card and 2) Adding your Driver's license to your Wallet. They are not related tasks.
You would have been asked to scan your license as part of the card application process. If it failed, see here:
Identity verification for Apple Card or Apple Cash - Apple Support
There is a link to more information on what to do if your ID verification failed.
If you try to add your license to the Wallet app, you need to have either an Arizona or Maryland license. Even if you do, adding one to your Wallet won't verify your ID for the Apple Card application.
