I copied a vocal track, then pasted it on a different track just slightly off to http://movieseriesworld.com/ get that effect. After that, the original track I copied is mostly in the left channel and I cannot get it back to center. Any advice?
Thanks!

Is it copied to a Stereo track or MONO?

If stereo:
Try using 'Split Stereo track to two MONO tracks' .. this splits the Left and Right side to separate tracks.
See if the resulting MONO track has more control.
