I see there is a Matomo plug in...
URL is set
Site ID is set
Enable admin tracking checked
content tracking set to All Content

main domain set to website URL

• Embeded Code? Do I need to past the widget infor from Matomo here?

In Matomo click in the top right menu on Administration ("gear" icon), then click on Platform in the left sidebar menu, then click Widgets.
Now you see a page where you can choose between two different iframe embeds.
Copy/paste one of those iframe widgets in the plugins Widgets: Embed code option.

there is a selection in Matomo called "Matomo Tag Manager", and it gived this code: does this look right?

var _mtm = window._mtm = window._mtm || [];
_mtm.push({'mtm.startTime': (new Date().getTime()), 'event': 'mtm.Start'});
(function() {
var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0];
g.async=true; g.src='https://analytics.waltrips.com/js/container_E6Nb4M2f.js'; s.parentNode.insertBefore(g,s);
})();

No, that's not the one.
Click on the little "wheel" next to Tag Manager and then as above.

Note that this statistics embed only works if you are logged in into matomo already as well. There are extra steps to make that work without apparently I never tried: https://matomo.org/faq/reports/requirements-for-embedding-matomo-reports/

OK... gear/platform/widgets

Looking there, I see Authentication, Widgetize Dashboards, and Widgetize reports.

I may not have asked the question very well.

• Is there anything I need to do to get Matimo to collect data from the website? other than installing the plug in, do I need to add anything to embed code?

No, a running Matomo install and general configuration is enough.
