Siteground CPU Seconds per month

Hello, We have a site that is hosted with Siteground and they keep shutting the site down because it goes over it’s allowed CPU seconds per month. the site doesn’t get a crazy amount of traffic, and I’ve made all the changes they recommended to try and fix the issue. They say that “it appears that there are a lot’s of MySQL executions and slow mysql queries running under your account”

and then I’ve got this:

Most of this is beyond me, but I see that some of the tables they mention have ‘wf’ as part of the title. Does it look to you like they’re saying it’s Wordfence that is the problem?

Any help would be appreciated.
