Get some (sugar free) rose water [0] and drink it. Compare with water. If they taste the same, you might be missing out on a lot of taste (but you will still be able to taste, say, salt vs. sweet).

More simply put though, if you definitely don't have a sense of smell, you most likely don't have a sense of taste either. I lost my sense of smell due to Covid for a bit, so I have some first-hand experience.
