I received a 1099 misc after I filed. What should I do?

Should I go ahead and amend my return since I have already received my refund. My extra tax I owe is $195 which isn't a whole lot. Or should I just wait and see what happens? I've heard that the IRS will send out a CP2000 stating my income wasn't correct and I'll owe x amount. If it's likely I'll receive the CP2000, I would rather just wait for it and pay it then rather then amending. Is that reasonable?
