Filed flight plan about 20 minutes before calling to see if flight plan was in the system. I informed Ground Control that I would pick it up in the air but was just checking to see if it had arrived.  Ground did not have flight plan so I started up and taxied to runway figuring it would be out by the time we were at the hold line. Called at the runway hold line and still no flight plan - Ground suggested I just take off and have the Departure Controller enter one for me.  Just to be safe I quickly filed another one on my phone; did my checks and when I called for takeoff they told me it had just come through.  I had filed NAVHO intersection then BLD VOR on the first flight plan; then just direct BLD VOR on the second - rest of route to ZZZ the same for both plans.On VFR climb I skipped NAVJO because I thought it was the second flight plan that had popped up on the system.  Phoenix Approach was in a long conversation with a VFR plane so couldn't contact until I was at 14;500 feet - climbing to 16;500.  They told me I was almost out of their airspace and to call ABQ Center.  Level at 16;500 I called ABQ and they cleared us to ZZZ as filed.  Here's where there was a problem.  Just to be safe I asked if I should be going direct NAVHO then BLD and the controller said 'affirmative' as I was climbing to FL280.  I knew I wasn't at NAVHO yet so entered it in as 'NAVJO' (incorrect).  I noticed that the needle pointed over 30 degrees to the right as I engaged NAV - figuring something was wrong I disengaged NAV and turned back to something close to direct BLD and asked if I could just go direct BLD which I was given.  NAVHO was pretty much on a direct line from FLG to BLD so I was doing okay before entering 'NAVJO' which is way up to the North.Looking at the track log I never was more than 17 degrees off and that was for as long as it took to reverse the turn; but this was embarrassing.  Don't want to do this kind of thing when departing a NY Metro area airport.  Contributing factors:  Flight plan late arriving at FLG.  My desire to do a quick turn and keep the boss happy - this was a fuel stop.  Misspelling 'NAVHO' because I was rushing - trying to keep the controller happy.  Two flight plans in the system; each with a different initial fix.  I neglected to enter NAVJO because it would be departing VFR and it was pretty close to the airport. Ways to prevent this from recurring:  File my flight plans earlier just in case - even if I'm not sure we will use it.  I thought we may be able to make it all the way to ZZZ so didn't file the plan for departing from FLG (fuel stop).  Don't be so quick to engage NAV - make sure it looks correct first.  Don't rush when entering waypoints - if I had entered with the correct spelling there would not have been more than a few degree turn to the left involved.  Enter all the fixes when departing VFR - don't assume you won't get one of them.
Small Transport pilot reported a track deviation due to confusion over two waypoints with similar sounding names; NAVJO and NAVHO.
