did you use painter's tape and remove it after polishing?
You aren't supposed to wax with the tape still on. The time to address the tape residue was after polishing when you wipe down the car to get rid of dust and polishing oils. IPA or mineral spirits would have probably taken care of it. Maybe a little diluted APC or adhesive remover.
After polishing and wipedown, the car should look like it's been waxed, even though it's got nothing on it. The wax is just the final touch to protect the finish.
Whatever you do now will remove your wax with the residue. No biggie, just rewax and consider it a lesson learned...
