Lost sense of smell after COVID-19, need help!

I would say my taste and smell is altered. I use red chili flakes on a lot of food so it has some taste. I never tested positive for COVID however a coworker did and we were in close proximity, This was during the time no one was commutating who was infected. Also lack of testing. I had a full work up by ENT doctor said everything looked normal.

I had covid pneumonia in January of 2021. I still have no real sense of smell or taste. I can taste food in that I can tell sweet, sour, spicy but I cant taste flavor. Many foods I once enjoyed have an off taste so I no longer eat them.
