Question Wiring 20amp, 220v dedicated line into panel

I need to get a 220v, 20 amp outlet wired into my 2nd story room. I assuming there needs to be a dedicated circuit for this in my panel. I plan to run 12 guage wire from the panel to the outlet and have a 2-pole, 220v, 20 amp circuit added to the panel. The panel is 150 amp and I have sufficient empty spaces. To make the job easier I was considering sending the wire through my cold air return since the cold air return vent is right above where the outlet would be. Is there any reason I should not send the wire through the cold air return? Also, I power down the main circuit at the panel and I'm ok to wire the new circuit in as long as I don't touch the hot screws at the top of the panel? Thanks.

You cannot run the cable through the cold air return. That would violate code.

You can route wire through the cold air return, but only certain kinds of wire and only with certain other precautions. For example, you cannot run ordinary Romex through. In most cases, it's a bad idea anyway.
