I see in the support documentation that there should be a CSS editor link in my toolset plug-in, but I don't seem to have it. Was it removed, or is there a way to add it that I'm unable to find?
Thank you for contacting us and I'd be happy to assist.
I'm not sure exactly which documentation you're referring to, but while editing Toolset elements, CSS editor is available at different places.
For example, while editing a Toolset Form, you'll the CSS editor under the fields.

And when editing a content template or View, you'll see the CSS editor in the settings pane, on the right side.

I hope this helps and please let me know if you need any further assistance around this.
That guide is related to an older plugin Layouts which is now put in a legacy status.
I'll not recommend activating it only for this global custom CSS feature. To include some CSS code globally, you can include it using the WordPress Custom CSS field at WP Admin -> Appearance or some third-party plugin: hidden link hidden link
