Looking to access your theme's code or language options with Shopify's new theme editor layout?
In your Shopify admin click on Online store > Themes
Next to the theme that you want to edit click on the Menu button which is a small square with 3 blue dots
This will open a submenu of options which includes: Edit HTMl / CSS and Edit Language
Click on Pages in your admin and open the contact us page.
In the Templates section for this page you will see a dropdown menu.
In here choose: page.contact and click save.
You will not be able to see this form in the Shopify editor but it will load on the customer side of the site.
Emails received from contact forms in your store will be sent to the Customer Email which can be assigned to the Settings > General section of your admin.
