My overflow broke, Now I have no filter just powerhead and running carbon, what should I do, How long will this last with no overflow, Thanks

I'd watch for signs of oxygen deprivation. How much flow does the tank have? Also, drop in a heater.

You have LR so that is your filter and always has been. If your heater is in the sump, put it up in the display until the overflow is fixed.

Your sump, skimmer and fuge, if you have a fuge has been mainly keeping nitrates down so there is no dire need to get it fixed immediately. If you do extra water changes, you could easily get by a long time.

Bertoni has a very good point about oxygenation that slipped my mind. Point a powerhead or 2 or 3 toward the surface of the water to help and even add an airstone till the overflow is repaired.

I'd stop feeding for the moment, too, come to think of it. The fish will be fine for week, easily, if they're in good shape.
