Hello there, @Julie Ocamica.
I'm glad you reach out to us for this concern. I have some information that will help you edit your ProAdvisor profile and update to version 19.
While I have this helpful article you can double check, publish and manage your Find-a-ProAdvisor profile, it would still be best to contact our QuickBooks Care Team since you're also updating the version to 2019. They have the tools that will assist you with the steps to successfully create changes on your ProAdvisor profile.
The following link contains the information to reach out support: How to contact QuickBooks Online Accountant support.
This information should get you in the right direction. Let me know how things turn out after speaking with our phone agents. If you have other questions aside from this, feel free to post a reply below. I'm always here to help.
