High Sierra Operating System

I am trying to load Turbotax2020 but it will not load because I am using High Sierra Operating system 10.13.6. Turbotax said that I need an operating system with 10.14. I checked an High Sierrra doe not have 10,14. So my question - Is there an operating system that I can use and what is the new of the system?My Mac was purchased in mid 2011.

High Sierra is the latest version of macOS a 2011 Mac can run. You would have to replace it with a newer Mac to install Mojave 10.14 or later.
