Hi, I have to update my OS to 14.6 but I don’t see notification on the settings that there’s a new software update for 14.6. Please help.

I have seen a number of topics similar to this and I am guessing there is something going on with Apple's servers generating this. I recommend trying again in a few hours and if there is still a problem then contact Apple:

Click here --> https://support.apple.com/choose-country-region Select your country, then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.

or:
