After using 3 TSO to seal one of Madara’ limbo. Naruto is seen with having 6 left. 
Then he uses a TSO to make a bijudama rasenshuriken. That means there’s 5 to go before he runs out. 
With more meteors falling, he spawns 7 of the same attack(Presumably, the five central ones used TSOs, while the ones on the end didn’t). Leaving him with no TSOs to spare. 
In fact, as IT was casted and while Naruto was protected inside sasuke’ susanoo, he is shown yet again to not have any TSOs on stand by. Once susanoo is released, you can see TSOs returning to Naruto’ back. 
This isn’t unique to Naruto either.
Not only was Madara’ lower half able to generate not a whole new set of TSO,
We shouldn't link to episodes/chapters on fan websites. You may link to Crunchyroll or other official website, but not those, please edit it out.
Also best use manga for the argument, just say chapter numbers and pages.
The only alive charater that can weild TSB is Naruto and by this point is pretty obvious that he doesn’t have it anymore. Regardless if he can reproduce them or not, as a character he will never use them again (at least it’s doubtful).
