Welcome to the Shopify Community! Happy to help troubleshoot this issue with you. Are you trying to have the product display on a particular page (for example, the home page) or inside a collection? Where is the product supposed to be showing?
If it belongs to a collection, make sure it's showing from the Shopify Admin under Products > Collections> inside the collection under Products
If it doesn't belong to a collection, do you have an all products page linked on your store?
Let me know how all of this goes, and once I have a little more information about where it's supposed to be displayed, we can keep troubleshooting! There are also lots of suggestions in this Community thread if you'd like to scan those replies.
