It's me again, I just want to chime in here before this thread gets confusing.
You're getting 6 templates here:
Because those are the only Content Template, the rest are Preset, preset is a saved styling/configuration of an element that you applied to another element (same type).
For example the Starter: Map preset, its a template that you can apply to the Map element
Read more details about Template Manager here.
Now lets back to the Themeco Block (Get In Touch) issue. The tutorial that you're watching is more likely using the X5/Cornerstone2 version where we have the themeco block.
But now with the X6/Cornerstone3, we have the Starter Pack on Template Manager unfortunately the Get In Touch block and other blocks from X5 are not part of the Starter Pack.
Nevertheless, I have installed an X5 on my devsite and downloaded the Get In Touch block, I have uploaded it here so you can import it to your Template Manager and load it to your pages.
And if you don't have a Google Map API key yet, you need to get one because you're going to need that in the Map element.

Hope this helps,
