Visual Studio for mac: how to run a terminal

Terminal window is not a part of the built-in tools within Visual Studio for Mac. There might be some add-ins or extension for this, but I am not aware.

However, there is a GUI Git tool called 'Version Control' which is integrated to VS, you can use it.

If you still want to use a terminal window, you can open a separate terminal window, outside of the VS. Alternatively there is an VS fro Mac add-in that allows you to open a terminal window (again outside of the VS) on any solution's dir.

UPDATE:
You can open any directory from Visual Studio for Mac in a terminal by right-clicking any project directory > Tools > Open in Terminal

Visual Studion for Mac Previews now include a terminal as of April 2020

Tools->Show Terminal Window or crtl+`

In Mac VS2019, I found access to Terminal under Solution navigation Select your Project Crl-Click (hold) Navigate to Tool Open in Terminal

It seems to work for me!
