Correct airport info?

hey guys,

so i’m still new to this game and I’m wondering how could I get the right airport info (taxiways & runways etc.) for each airport? I know the build-in data are messed up for most of the airports and I downloaded some airports on flightsim like KCMH, my home airport but if I want to fly on vatsim, how could I know the controller and I are on the same page? Like if I have the correct version of KCMH and the controller doesn’t, does it make a differennce when I get a taxi instruction from the tower?

thanks =)
