Google Analytics Ecommerce Trouble shooting

Hello! I've recently started managing the Analytics of a sitefinity based site. For background we do not use the Sitefinity ecommerce solutions though we have updated to the most recent version and do have a store. We are getting some ecommerce data sent to Google Analytics but it doesn't appear to be correct and I can't find where this data layer is implemented. We use tag manager and there isn't a data layer in our implementation and ecommerce isn't turned on in GA...so I'm sort of confused as to where this information is coming from. Other than the templates is there any where else I should be looking? A special sitefinity widget I should look for? Thanks!!!
