and the called back TD on TT was the correct call

Live Ball Becomes Dead
ARTICLE 2. a. A live ball becomes a dead ball as provided in the rules or when
an official sounds his whistle (even though inadvertently) or otherwise signals
the ball dead (A.R. 4-2-1-II and A.R. 4-2-4-I).
b. If an official sounds his whistle inadvertently or otherwise signals the ball
dead during a down (Rules 4-1-3-k and m):
1. When the ball is in player possession, then the team in possession may
elect to put the ball in play where declared dead or repeat the down.
2. When the ball is loose from a fumble, backward pass or illegal pass, then
the team in possession may elect to put the ball in play where possession
was lost or repeat the down (Exception: Rule 12).

it would have been a touchback if:

Out of Bounds
ARTICLE 4. a. Backward Pass. When a backward pass goes out of bounds
between the goal lines, the ball belongs to the passing team at the out-of-bounds
spot.
b. Fumble. When a fumble goes out of bounds between the goal lines:
1. In advance of the spot of the fumble, the ball belongs to the fumbling
team at the spot of the fumble (Rule 3-3-2-e-2).
2. Behind the spot of the fumble, the ball belongs to the fumbling team at
the out-of-bounds spot.
c. Behind or Beyond Goal Line. When a fumble or backward pass goes out of
bounds behind or beyond a goal line, it is a safety or touchback depending
on impetus and responsibility (Rules 8-5-1, 8-6-1 and 8-7) (A.R. 7-2-4-I,
A.R. 8-6-1-I and A.R. 8-7-2-I).
At Rest
ARTICLE 5. When a backward pass or fumble comes to rest inbounds and no
player attempts to secure it, the ball becomes dead and belongs to the passing
or fumbling team at the dead-ball spot.

The fact the HUGE hold that set up the TD in the first place was completely ignored is ridiculous.
