Hi, @SillyShirts
Thanks for posting to the Shopify Forums.
It sounds like you are attempting to verify your information for Shopify Payments, and have input an incorrect birth date. If this is the case, you will need to reach out to our live Support Team via the Help Center who can escalate the situation to our Shopify Payments team for rectification.
Best of luck!
