How do I adjust form forward setting?

Are you referring to the Email Notification or to the Thank You Page?

The Email Notification is the email alert that you will receive when someone completed your form. You can refer to this guide if you want to create one: https://www.jotform.com/help/25-Setting-up-Email-Notifications.

If you are planning to redirect the user to a specific page, then you can redirect the Thank You Page to an external URL, here's how: https://www.jotform.com/help/38-Redirecting-Users-to-a-Different-Page.
