为什么我的Users / myname / go文件夹不存在?

When I type in go env it shows me the path Users/myname/go

I can use go from the terminal, I can even run a go file... When I open GoLand it says GOPATH is empty. I can't even set my go path there because I can't find the folder to select on. I try to cd into the directory from Users/myname and It still doesn't work. I am extremely confused here.

I have added both of these to my bash_profile even though I read it isn't necessary anymore.

export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$PATH

What is going on? Why don't I have this folder?

EDIT: I downloaded it from here https://golang.org/dl/ for mac

I believe I found the folder under /usr/local/go

I should have read this.

Download the package file, open it, and follow the prompts to install the Go tools. The package installs the Go distribution to /usr/local/go.

The package should put the /usr/local/go/bin directory in your PATH environment variable. You may need to restart any open Terminal sessions for the change to take effect.

Edit: also this comment helped as far as the correct command. "where go"

Why doesn't my Users/myname/go folder exist?

Thanks, leaving up for anyone else as confused as me.
