Questions About Dr. Strange's Prediction/Endgame Ending

[Triton]

Please forgive me if these are stupid questions...

The writers of Avengers: Endgame have stated that the "one" way Dr. Strange foresaw Thanos being defeated was Tony Stark/Iron Man dying and the Infinity Stones being destroyed.

My question is this...

At the end of Endgame, Stark dies because he stole the Infinity Stones off of Thanos' gauntlet and used them to defeat Thanos, resulting in Stark's death from the release of energy from the stones.

But the stones weren't destroyed at all at the end of Endgame. They were taken back to the past by Captain America. So, why weren't the stones destroyed like Dr. Strange foresaw?

And how does taking the stones back into the past prevent anything from happening again?

The stones in the present were destroyed that why they needed them from the past. So now in the present the stones are just atoms spread through the cosmos.

How were the stones destroyed in the present???

Thanos destroyed them himself, the energy output from that was how the Avengers were able to find him on the garden world.

As Banner (and another character) explain, in the MCU, time travel doesn't alter the past, it just creates a parallel universe based on the changes you made (like stealing an Infinity Stone and leaving a wizard without the tool to stop an evil entity down the road), which continues to exist unless the change is undone (like putting the Stone back), thus "cutting off" that branch before it can continue.

So, basically, the Avengers changed nothing in their history, but brought alternate versions of the Infinity Stones from other parallel universes to this one and used them to fix things in the present and then put them back to keep the multiverse running smoothly.

Actually, Banner (and another character) explained that time travel doesn't alter the past or create an alternate timeline. Only removing an Infinity Stone does that.
