Create link to users created content only I have a content type Business, When a user creates a business and then signs into the site, I have a link called "my business" that when the user clicks on i want it to take them to only their created business. 

Not sure what to "link" too for this to happen.
You can link to a view, that filters the content type Business and the current user. 

This is a similar question for D7, I think both solutions provided there work in D8 the same way:

Filtering on node whose user ID is equal to the current user
