Bo here from Shopify Support!
That is a great question. The code file that you will most likely need to change is the page-contact.liquid. Here you will see the code broken down into parts like so:
In order for me to help you with this, I will need to know what you want to hide specifically. What is it that you want to hide and why? Next, I will need to know the name of the theme and a link to the contact page on your store. I would highly recommend reading Help Us Help You which goes through all the information we need for you to share with us in order to help with theme-related questions.
All the Best,
- your store URL;
- page URL with the issue you mention;
- storefront password (if your store has one).
