I simply create a Note on my iPhone, press Done. Open Notes on my MBP and after a few seconds the note I just created is there.
Not sure you really have to "do" anything?
Why would you answers a question like that, if you don't know how to answer just don't post anything..
This is really bad from apple, I don't like to use sync with iCloud, but it's the only way to sync notes, you create folders... in my iphone... in icloud... my previous notes wont sync to my mac, only the new ones i create... it just don't work..
But well, I suggest you email the notes to yourself in case anything goes wrong.
What I did was in iphone/settings/icloud select to sync notes
Go to my Mac/system preferences/icloud an select to sync notes
When you create a new note in the iphone and want to sync it to your mac, you have to be in the icloud account when you create it, otherwise it wont sync to the mac, it's just plain stupid from apple, but what can we do.
