I don't believe it's a touch back. It should be a safety.
The ball is not dead at the last moment of playback, therefore either the play should continue, or the ball bounced out of bounds.
NFL 2019 11-5-1 should be the rule that applies.
It is a Safety:
(b) when an impetus by a team sends the ball behind its own goal line, and the ball is dead in the end zone in its possession or the ball is out of bounds behind the goal line.
Madden makes this call the same way, but that doesn't make it correct. We should be better than Madden.
