Your forks are probably a bit skewed in the yokes. If you slacken the 2 pinch-bolts on the lower yoke of the steering head (they clamp the forks into the bottom yoke there), stand in front of the bike, hold the wheel between your knees and twist the handlebars the correct way, you may find it all comes into line. If nothing else is amiss, it ought to. Worst case something's bent - but hope not. Good luck!
