on an ifr flight the center or the tower will tell you the first way point after that usally they tell heading to set in the autopilot to turn like “turn right heading 075” but when it is the time for the final how do you know what you must do to align the airplane with the runway for landing?
thank you

Welcome! When flying IFR, you’ll usually be cleared for an ILS, Localizer or RNAV approach. For ILS or Localizer, you need to tune your aircraft’s ‘NAV radio’ to the right frequency for that runway, and set the autopilot to NAV. That will make the aircraft line up with the runway automatically.
For RNAV, it’s similar, but you program the flight computer instead of tuning a radio frequency. Again, set the autopilot to NAV and it will automatically line you up at the right time.
In some places, the USA particularly, you’ll be cleared for a visual approach. In that case, you can just look out of the virtual window, but it’s fine to use the NAV autopilot as well to help you.
Here are some excellent YouTube videos to watch about it:
Every aircraft is slightly different so don’t worry if its confusing at first 
You can always practice the approaches offline if it feels too overwhelming with VATSIM as well.
When you are “cleared” for the approach, you can follow the published approach. An example might be “turn right heading 075, cleared ILS approach runway 10”. Once you intercept the localizer you can turn onto final and descend on the glide slope without further instruction.
you can expect on average to establish ils around 9nm at 3000ft when set up…atc will usually give you a final vector to establish ils or you can run a r/nav appr which will take you to final with atc on standby…
