Git-it "fatal: ambiguous argument"

Somewhere in the workspace I think I must have introduced another branch and called it the same name as the one I am trying to commit a change to. How can I find it? Is my only option to delete the workspace and just start the tutorial over again?

olddognewtrix123:~/workspace/kloneklone/patchwork (add-olddognewtrix123) $ cd contributors
olddognewtrix123:~/workspace/kloneklone/patchwork/contributors (add-olddognewtrix123) $ git status
On branch add-olddognewtrix123
Untracked files:
  (use "git add <file>..." to include in what will be committed)

        add-olddognewtrix123.txt

nothing added to commit but untracked files present (use "git add" to track)
olddognewtrix123:~/workspace/kloneklone/patchwork/contributors (add-olddognewtrix123) $ git add add-     olddognewtrix123.txt
olddognewtrix123:~/workspace/kloneklone/patchwork/contributors (add-olddognewtrix123) $ git commit -m "hope this works!"
