How to enter activation code

Hello everyone.
My issue is this. I recently bought one year activation norton code from a local store.
I just downloaded norton fromm the website in the standard package and it has one month free use and then ii will start charging me.
I cannot find where I should enter the activation code I bought! And I’m afraid I will be double charged when the free month is over.

Please help.

and you registered new purchased key with your Norton account?
and you signed in at your Norton product?

No i haven’t registered any key. Because it is on 1 month trial. So I guess I cannot enter my key until the trial is expired? Maybe?

new key starts new term
and you signed in at your Norton product?
arrow top = user account
arrow bottom = mouse hover Enter a Key

OMG! Thank you so much. It was right there. I wish you Happy Holidays!

Okay…Thanks
