Weird smell won’t go away

I’m starting to think it has something to do with Covid from last year. My tastebuds haven’t recovered. On first biting into something I can taste it and then the taste starts going away the more I eat, but maybe sometimes a taste will come back in the middle of the meal, and now I have a smell that I smell all the time in my home and I’ve cleaned everything and no one else can smell it but now when I go to other places, I’m starting to catch glimpses of that smell. I’m pretty sensitive to most artificial odors already. Is that maybe be part of long Covid? I can’t get a hold of a doctor to give me any answers, no matter what I do.
