A Contact Page was generated for you automatically during installation and added to the menu. If you already had a contact page or if, for whatever reason, the link in the menu goes to a 404 page, you can locate this page under Pages > All Pages in your dashboard.
You can also create a contact page manually by creating a page and then, while editing, locating Page Attributes (Template if 5.8 and above) and selecting Contact Page Template from the dropdown list.
Our contact forms are designed to be a simple/basic alternative to forcing you to download another plugin. It sends emails to your WordPress admin email address. If you don’t know what that is, you can find it under Settings > General.
