Like a non-interactive rebase, you have to rebase onto a particular commit.
With a non-interactive rebase, if you supply a direct ancestor of the current commit then you aren’t changing anything; with an interactive rebase you can edit commits after the commit that you are rebasing onto, even if the commit is a direct ancestor of your current commit but you do have to specify this commit that you want to edit onwards from.
I don’t know the details of your situation but you might want something like this:
# Opportunity to edit or prune commits between origin/master and current branch
git rebase -i origin/master
or
# Edit some of the last ten commits
git rebase -i HEAD~10 # Note that ~10 uses a tilde("~") not a dash("-"_) !
