I ordered a new bolt, but my fear is that I damaged the threads in the crankshaft. I assume I can chase the threads if that's the case but it's not something I have any experience with. Any suggestions?

Once you get the new bolt so you no longer need the old one you can clean the threads up on the old bolt and cut 2-4 slots lengthwise on the old bolt and use it as a thread chaser to clean up the crank.
