I installed this 100 amp Homeline panel. I realized after I installed it that I hadn’t grounded the box. As seen in the picture I have two 120V hots and a neutral. I’m not sure if I can use the neutral as a ground or if I need to install a dedicated ground.

Your metal conduit may provide a ground path. See the linked duplicates for more on that. If so, you may need to bond your neutral bus bars so that they're also grounded. – isherwood Mar 13 '23 at 18:23

Yes, you need a dedicated ground path that is separated and isolated from the neutral wire. The shell of non-flexible metal conduit will suffice. Grounds must be kept isolated from neutral. (the only exception is a pre-2008 subpanel which was wired with neutral-ground combined, or "Protective Earth And Neutral" as the British call it. Terrible idea, that. – Harper - Reinstate Monica Mar 13 '23 at 19:41
According to other posts, this is a subpanel. – Harper - Reinstate Monica Mar 14 '23 at 21:35
