Your screenshot mentions both Facebook as Google Tag Manager. Both assets to do not come with Joomla core. So there must be some kind of 3th party extension that adds this.
Google Tag Manager https://www.googletagmanager.com/gtag/js?id=UA-110217943-1&l=dataLayer&cx=c
The same goes for connect.facebook.net... It is a connection between your site and Facebook. If there is no need, then find out which 3th party extension is adding the Facebook pixel. Just after the start of
<body> and before

You can run a Joomla website locally using an "AMP" stack (like LAMP, MAMP, WAMP, etc). With Akeeba Backup you can create a backup that you restore locally.
If you create an SQL dump from your Joomla database, and put that text file in your local Joomla folder, the IDE will also search in that.
