You have to put the waypoint into the flightplan for it to come up on the HUD if I rememember correctly. Bring up the FPM page and open the current flight plan. PG down on the FPM page until you see the last waypoint in the Flightplan, type in the name of the waypoint you created, JT1 and then press the OSB on the right, can't remember what it is off the top of me head...
If that happened right, you it should see it come up as a waypoint with your others on the HUD along with Init Position etc.
