If the light from a quasar took 13 billion years to reach us, then the quasar was 13 billion light years away from us 13 billion years ago.
13billion light years would be the estimate and distance to travel to and from not talking about years.
Loosely speaking, that is the distance that you would get if you could somehow take a snapshot of the universe at the present and measure the distance to the quasar using a humongous yardstick. You can't do that, of course, but if you make some assumptions about the amount of matter and dark energy in the universe, you can calculate the proper distance from the redshift of the quasar, which you can easily measure with a telescope and a spectrometer.
i think i lost you when i didn't mention the the light years being distance.
