Being Sedona residents, we get asked about where the vortices / vortexes are all the time.
Here are the four. Some folks who will swindle tourists out of money will claim there are more only they know about but none of them are universally recognized as these four are. That said, they're pretty and offer nice vistas, but there is nothing inherently special about any of them other that what people claim without evidence that they feel.
Sedona Airport Vortex (on the outcroping to the northeast)
Bell Rock Vortex, the exact location is -- unsurprisingly -- unclear.
Boynton Canyon Vortex, overlooks Enchantment Resort
Cathedral Rock Vortex, like the Bell Rock Vortex, the exact location is unsurprisingly unclear.
