Hi...based on your history...loss of smell has many causes...covid 19 should be ruled out first...since the symtoms are there since 45 days...you might have recovered by the time of testing...anosmia due to covid takes atleast 7weeks (on avg) to recover!!
And other common diseases like sinusitis,allergic rhinitis,deviated nasal septum, certain drug can also cause anosmia....
Next Steps
