How to remove duplicate google analytics code? | Configuring All in One SEO Pack Pro | Support | Semper Plugins

I am currently using “Insert headers and Footers” to place the google analytics site code into my site. Everything is checked and verified. I have not visited my google analytics dashboard in many years. When i did get back in there.. I noticed my bounce rate went to 0% so I must have another analytics account set up? I may have done this many years ago, but i can not find the code to remove. How do i do this? i want to keep the code I used in the “Insert headers and Footers” plugin, but remove the other code that got installed years ago. I looked in the footer, and header section in my WP site and could not find any of it. I don’t have any other plugins inserting this type of code anywhere else.
