Once the branch is created, you can't force its creation, because it is
already created. Just

git checkout "branch_name"

is sufficient at this point. git is correct to complain that you are trying
to create a branch that already exists.

git log --decorate --oneline --graph --all

will show you where your branch points in history at any given moment in
time in a convenient form.

In this case, you are asking git to create a branch named -f (the -b branch
option). Then "branch_name" becomes the reference that would be used to find
the commit that -f would have pointed to. However, -f is not a valid name
because it is an option and git is correct to reject it.

git checkout options are described here:
