I don't think my 9082 has anything quite like that. Pin 13 of IC20 is connected to 0V, so I expect the other end of the capacitor connects to pin 16, which goes to the 12V supply via R84. It looks like it is just adding a little more decoupling. R84 will be getting hot if that tantalum capacitor has gone short circuit.

There may still be another short somewhere else on the 12V line, you'll know once you have replaced this faulty capacitor.
