This is a loaded question without definitive answers. There's no magic list of where you can apply and where you can't. You should take a look where students have matched from your previous classes from your school as well. You're obviously more competitive for FM without Step scores, but you'd be fine with community IM and maybe a few low-tier university IM places that might take DO students without Step scores. As for fellowships, they care more about where you go to residency, aka they'd like you to go to a University IM place if possible, but that doesn't mean you're closed off if you go community, but it will make things harder, depending on what fellowship you want to match too. Also, I'm hearing more and more that fellowships are wanting to see Step scores as well.
