Ted here from Shopify, thanks for posting your query!
If your payments are on hold, this would be account specific which we’re unable to support on a public thread via the Shopify Community. When you have a moment, please contact our live chat, email or callback support here so we can authenticate your account and take a closer look into this with you. Here's a video example of how to contact our support if you need it.
When you log into your admin, if you can see a red banner asking you to upload certain documents (such as this screenshot), please do so when you have a moment. Our Shopify Payments team will review everything in full and will update your account within a few business days. Our support advisors can provide more information too if you need it as mentioned above.
If there is anything else I can help you with, please let me know, I’m happy to help!
