I paid full price for Office 365, yet I only see Word 2010 on my PC

john_antonacci Good day!

On the screenshot that you have provided, I can surely say that your product is Microsoft 365. I think the misunderstanding comes in the Version 2010 here. It does not mean Office 2010 and if it is Office 2010, it should look like this: 

The Version 2010 that you are seeing on your screenshot with Build 13328.20408 is the version and the build number of the Current Channel of Microsoft 365 that was released last November 17, 2020. 

You can see the update history for Microsoft 365 Apps (listed by date) here:

I hope this information may shed light on your concern.
