Covid negative literally hundreds of times. I am a healthcare worker and tested at a minimum twice a week for over a year. The smells started first and then seeing things.

You can say that with literal certainty given that test schedule!
I found this link and took an excerpt from it that you may find helpful (below).
– Phantosmia: Common Causes
While the symptoms of phantosmia can be alarming, they’re usually due to a problem in your mouth or nose rather than your brain. In fact, 52 to 72 percent of conditions affecting your sense of smell are related to a sinus issue.
Nose-related causes include:
irritation from smoking or poor air quality
Other common causes of phantosmia include:
upper respiratory infections
exposure to neurotoxins (substances that are toxic to the nervous system, such as lead or mercury)
radiation treatment for throat or brain cancer
Do any of those symptoms resonate? (I realize that still isn't addressing the visual symptoms.)
