The furthest things we now see are now what, 50 billion lightyears away? I don't understand where the 13.8 would even come into play as a distance, but I am happy to be told
That is why I put the google search in, and why I put the NASA link in. It still amounts to going with the experts. I'm seeing articles claiming varying distances, which is confusing to a layperson. I'd say get your info from NASA or Neil for that matter.
