pushed branch not visible on github

Question

I've made some changes and to a branch, commit them and pushed it but I still don't see the branch (nor the commits) on github (or can't pull changes to another machine). What I've tried already:

$ git branch       *MyBranch
                   main
$ git push         Everything up-to-date
$ git branch -vv   *MyBranch 76e9e79[origin/MyBranch] last commit message
$ git status       On branch MyBranch
                   Your branch is up to date with 'origin/MyBranch'.
$ git remote show origin MyBranch    tracked
      Local branches configured for 'git pull':
      MyBranch merges with remote MyBranch
      main                     merges with remote main
    Local refs configured for 'git push':
      MyBranch pushes to MyBranch (up to date)
      main     pushes to main                     (up to date)

What's going on, why is MyBranch not visible on github nor available for pulling on another system?

In response to @ElpieKay's comment:

$ git remote -vv
origin  git@github.com:org/repo.git (fetch)
origin  git@github.com:org/repo.git (push)

git push origin MyBranch:MyBranch
Everything up-to-date

I'll start over from scratch, get a fresh clone and copy across the files I've changed.... luckily the changes are manageable in size.
