I assume you have a sand filter if so you most likely have broken laterals in your filter. A lateral should allow water through but not sand. if you have a DE filter and you are getting what appears like sand in the pool, you have one or more of the filter grids that have holes and the DE is passing through the filter grids back to the pool.

I accidentally vacuumed dirt in my pool using backwash mode instead of waste mode. How do I get the dirt out from under the sand?

There wont be any dirt under the sand. When you vacuum your pool you should do it on filter mode Otherwise you will lose a lot of water for nothing, this would be especially wasteful in the case of a salt water pool. Ofter having vacuumed the pool on filter mode and if the pressure gets too high backwash. after backwash rinse for a minute, then return to filter.
