I did the check as recommended in this infographic, which does not involve a smell test. Not sure how I would get the proper materials and setup to do a smell test at home—some smells are gasses which presumably would not be blocked by any mask? You would have to find some kind of material that generates smelly aerosols at precisely the right size.
Did you do any smell testing to see whether the mask fits in a way that makes you unable to smell things?

https://success.ada.org/~/media/CPS/Files/COVID/Conducting_Respirator_Fit_Tests_And_Seal_Checks.pdf suggests a few ways to do proper smell tests.
The one with saccharin which leaves a sweet taste in your mouth without seal seems to be the easiest to do at home.
I personally did some testing with cider vinegar and found that a FFT3 mask reduces the smell when properly fitted.
