Do you need a neutral when running a BLK Red and ground from a panel directly to a 240V 4800W 20A heater outlet?

No. The black is 220, the red is 220, and the ground serves as the neutral.

the last answer "no" is correct but the reason is not. the ground is still a ground. the red is 110v and the black is 110v. together they are 220v. the neutral or (common) is for a 110v return. for example a stove or a dryer will have 2 hots a common and a ground because they use 220v and 110v. 220v to power the heating elements and 110 for the controls, light bulbs or the outlet on a stove. A construction heater only uses 220v and only requires the two hots and the ground for safety.

Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.

This is an indication that your heater core is leaking. To stop the leaking you will have to replace the heater core or stop using your heater.

If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.

No, not really. The two hot legs can be opposite legs of a 120/240 V split phase power source. You still do need a protective earth ground, however, but the heater itself does not require a grounded neutral to run.
