If you're looking to update the information on your 1099-K form, you'll need to get in touch with our internal support team so that we can help you with securely changing this information on your account.
You won't be able to update this information from your end via the Shopify admin, as these details are stored in your Shopify Payments file that only our internal accounts team has access to, for security reasons. So your next step here is to reach out to our live support team via the Help Center here. Once logged in, select a topic that best fits your query or situation. From there, you'll be taken to a page with a list of relevant support articles, and you can scroll to the bottom of that page to select your preferred contact method with our team. Our live support team will then be able to further assist and escalate your case to the relevant accounts team, so that we can help get your Shopify Payments account information updated.
