2 years since my rhinoplasty and septoplasty, I cannot smell anything. Should I be worried?

Hi, I underwent Rhinoplasty & Sepoplasty as one operation in August 2020 and there are a lot of issues that I am facing today since post surgery. Firstly since a week after the procedure I have not been able to smell anything and I thought it was covid related but it has been nearly two years now and has had affected my life so much I don’t know why I haven’t been able to smell anything for this long I’m really worried.
