Hello, Douglas opted out. I will help you.
Tell me if you are in heating or cooling mode. If the furnace is leaking water in cooling mode (summer time) it is not the furnace that is leaking but the cooling coil sitting on top of it in most cases.
There are two copper tubes attached to that, those run to the unit that sits outside. If that is the case here, it is the drain pan that sits under the cooling coil that is full of slime and debris and over flowing.... it needs to be cleaned out.
If it is winter where you are, there is a similar situation going on inside the furnace.
I will coach you on how to rectify the problem in either case.
Please send me a few pictures of the furnace taken from about 8 feet away so that I can see what you have, and tell me the name of the nearest city so that I can assess the weather.
Use the paper clip icon at the right end of the tool bar above to attach the photo's.
We can go from there without a time limit.
