Can I use 12/2 wire for a 20 amp line?

Yes, but you might want to think about a ground lead too, it might be
code required. G

Do you _really_ think that if you walk into an electrical supply house and ask
for a length of 12/2 cable, you're _not_ going to get cable with black, white,
*and* ground?????

To the OP: ignore Jeff's post. If you're running a 120V 20A circuit, 12/2 is
what you want -- it has the ground included. Don't buy 12/3, thinking that you
need that to get the ground wire. You don't.

12/3 will actually have 4 wires: black, white, red, and bare.
