Can someone please explain this to me? My engine light has been on and when taking it in for oil changes no one seems to think its a problem. Today I was getting my car inspected and was told this and that it failed but the individual acted like he did not want to take the time to explain this to me. I have never heard of this before.
Not much back by the firewall thats going to leak other than the heater hoses. it would help if you identify the liquid? How much of a puddle does it leave under the car when parked overnight? or is it only leaking when the motor is running, are you running low on any fluids? like coolant, brake fluid,power steering fluid? transmission or engine oil?
Uh, do you mean there's a leak by the FLYWHEEL or FIREWALL? Two vastly different things. Pretty sure you meant flywheel, which means you probably have a leak from your water pump.
That can certainly be a big deal, best to have a qualified shop look at it. You may be in need of a water pump replacement. Failure to do so could result in your car losing all coolant, overheating, and destroying the engine completely if you don't catch it in time.

I meant firewall, sorry, I always mix those two. So since its the firewall what should my next step be?

I noticed it only leaks when running now that I look at it.
A water leak at the firewall would seem to be a heater core leaking but I can't imagine why that would fail a state safety or emissions inspection.
Low on coolant, engine not operating in it's specified range to be fully warmed up, most will fail emissions testing if engine isn't at operating temperature. And that would be the only reason.
Sounds like the OP has a leaky heater hose or heater core (hence-leak near firewall)
loss of coolant = thermostat not opening fully = coolant not circulating = engine not up to operating temperature.
But, on newer model cars, when the emissions inspector plugs the diagnostics into the car, it will tell the user if engine's emissions are within parameters required, onboard computer sends all information to tester's instrument, and will give information that engine isn't operating at the right temperature and which sensors are recording/flagging emissions controls. Engine does not to be running when newer cars are tested, record of operations is stored in the onboard.
Failure for High CO; CO is an indication of a Rich mixture. This is, too much fuel entering into the cylinders or not enough air. If a fuel injector is leaking into a cylinder, that cylinder will be running a richer fuel mixture causing it to run out of air and the flame burn out before the fuel is consumed properly. This is like turning off the vents on your charcoal grill and the fire goes out. The fuel is partially burned but, not all the way consumed. Engine temperature is a factor in how much of the fuel is burned. Cold engines cannot burn the fuel as well as an engine at operating temperature.
