Hi,
Please go to Admin -> Add/Edit Product ->Right side column Publish settings -> Here you have one option that is catalog visibility, check this .
There is another option at Admin -> Add/Edit Product
Inventory tab
The inventory tab allows you to manage stock for the product individually and define whether to allow back orders. If stock management is disabled from the settings page, only the ‘stock status’ option will be visible.
Thanks 🙂
With Best Regards
