While it probably doesn't affect site performance, Google does not recommend having more than one gtag.

Most browsers will not open more than four to eight HTTP requests to a single domain at a time. If you have a high number of tags on the same domain firing under the same conditions, tags will only fire within this browser limitation.

Thank you both for the prompt assist.
I am only using the G4-Analytics plug in.
As you can see in the page source, the gtag id is the same in both location.
Code:
<script async src="https://www.googletagmanager.com/gtag/js?id=G-JQL28SP4BW"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'G-JQL28SP4BW');
</script>
<meta charset="utf-8">
<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-JQL28SP4BW"></script>
I made a test ( maybe pointless) but oddly if i change the gtag ID in the G4 Anlytic admin setting, the ID changes in both places.
I may just uninstall G4-anyltics to see if the script is still loaded. Not sure why the script would be loaded twice on the same page
