Narrative:
We were cleared direct nrrli on the serfr 3. I line selected narwl; brought it to the top of the legs page; and confirmed with the captain 'looks good?' he replied 'looks good.' a while later; approximately 10 miles south/southeast of point nrrli; ATC asked 'are you direct nrrli?' the captain replied 'affirm; direct narrli.' we then both reviewed the STAR and the captain noticed point nrrli. We then reloaded the STAR and headed directly towards nrrli. Once we executed the direct nrrli; the aircraft turned approximately 10-20 degrees from our previous heading to narwl. Nothing more was said from ATC; the rest of the flight was uneventful.
