Well I'd guess that if the OP used a turbo that's rated at the 20% mark it would have been possible to have managed it differently to achieve something close.
To start with, heating apple juice often causes problems with pectin hazing, but also gives the juice a "cooked" taste. The whole point of not heating it is to reserve some/all of the "fresh" taste of juiced apples.
Equally, while the turbo's normally do have nutrient mixed in already, it's possible that the ferment had munched it's way through the available nutrient, hence it seeming to stick at 1.050 (which is at the upper end of sweetness/measurements when testing commercially available sweet meads).
Something like mixing the juice/honey, pitching the yeast, then aerating it daily until it gets to the 1/3rd sugar break, and then adding something for additional nutrient - maybe FermaidO or at least some boiled bread yeast.
He mentions a drop of about 100 points of gravity, which would represent about 13.5% ABV, and while it doesn't always, the alcohol hot taste will mellow out.
Turbo's aren't usually meant for the taste, more for just fermenting sugar to produce a "wash" that can be distilled for neutral alcohol (license required for that in most places/countries). Plus a little research found that most of them are designed to go to about 14 to 16% ABV, with a few rated higher, so it probably would have been just as effective to use a champagne yeast, proper nutrition/aeration etc.
Though if he's happy with his results, then that's just as good eh !
