How do I find and delete Meta pixels?

3 part question:


I have a fb pixel on two websites in META, but I only have only one website. One is targeted correctly, but the other is pointed to the url I use for editing my website. Should I and how do I find and delete one since I don't think I have custom code anywhere?

I also can't complete conversions API that Meta is requesting (according to Squarespace assistance,) is there anything to do here?

In addition, Meta is also showing me two other pixels that I cannot allocate anywhere on my website.


I really just want to keep things a simple and streamlined as possible, but also hoping to increase my seo and website visits. Squarespace assistance has referred me here since they can't include this in their scope of assistance. Thanks in advance!
