Ok is the line completely insulated or is some of the copper exposed?
OK that all needs to be completely insulated or you will have condensation forming and dripping especially if the area they are in is warmer and humid and not dehumidified. Go to the hardware store and they sell pipe insulation by the roll. Wrap it good and it should be fine.

Which line is leaking? The condensate line should be rubber off the plenum
OK do you see the condensate rubber or hard plastic drain tube connected to the ductwork?
Yes disconnect the white plastic condensate line and see if it is clogged up in the port
Remove that RED PLUG
Ok is any water coming out of there and is it plugged at all?
Can you blow it out? That one they glued in, I hate that...so you may want to cut the pipe and get a flexible piece of rubber tubing to make the coupling then you can clean out the drain pipe and blow or snake up into the condensate pan. I think you just have a algae blockage.
Yes you have a blockage likely in the white PVC pipe...I would cut it right before it makes that elbow and get a couple hose clamps and a hose to make the connection back there again, that way you can clean the line in the future.
No that should be it, try it out and see. Let me know what you find
OK peel back the Black insulation on that larger copper line is it iced?
