Don't think I've got TBT turned off. I think the GPX files I use just don't have that information. 'Distance to destination' and 'Distance to next' are always identical when I'm using routes I've downloaded, which suggest that the routes don't have any information about turns. I've used TCX files but can't recall any cuesheet information, but it's possible the TCX files I was using simply didn't have them.
The GPX files don't contain TBT info, it's your Garmin and its installed maps take the GPX track and then give you TBT. That's why it takes a bit of processing when you select 'follow course'.
I don't know about that distance to next stuff. I don't use that.
