If you see multiple pages for the same business in your account, start by checking what types of pages they are. It's possible that you created a Brand page in addition to a Local page. How to tell the difference? In Google My Business, a Local page will show the street address below the name of the business. A Brand page will not.
In this screenshot, the listing on the left is a Local page; the right is a Brand page. Information on Brand pages does not appear in Google Maps.
For next steps, choose the follow up questions that corresponds to what you see in your dashboard.
