git “uncheckout” by 'reset --hard' does not produce expected results

Question

I mistakenly created a remote branch (MY-12345-own-branch), then did a checkout on it. So, if I do git branch --list I see:

* Team_Branch_01
MY-12345-own-branch 
master

I would like to delete ("uncheckout") MY-12345-own-branch, so that I remain with:

* Team_Branch_01
master

However, when I perform:

git reset --hard origin/MY-12345-own-branch
git branch --list

Nothing appears to have changed -- I am still getting:

* Team_Branch_01
MY-12345-own-branch 
master

Why?

What am I missing?

Answer 1

Command to delete a branch:

git branch -d <branch_name>

If the branch has not been merged, use

git branch -D <branch_name>
