How do I move forward?

In 2019, I filling for my father, brother, and myself, but all three names were spelled incorrectly. I'm not sure what happened, but it wasn’t fixed. Last year, my father was contacted by the U.S. visa embassy and asked if he was still interested, to which he replied yes. He migrated a year and a few days ago. I would very much like the opportunity to do the same, but with my current age (27) and because my name was or is in the system, how can I get an appointment or guidance on how to migrate as well?
