Any refutations to Heggarty et al 2023, which challenges the traditional steppe theory of spread of Indo-European Language ?

What are you talking about? The paper doesn't claim anything that you just said. This is a huge misunderstanding on your part.

The paper is highly contested, especially regarding the hypothetical earlier Anatolian branch of the Indo-European expansion. However, it doesn't claim that the Indo-European languages came to India-Iran in ~4000 BCE, nor does it claim that the IVC was already Indo-European-speaking.

Sounds like someone browsing through some paper kind of distractedly at high speed, just caught the number 4,000 (which was like maybe saying "4,000 years ago"?), then possibly erroneously thinking deciding "4,000 BC" in his own mind.

Then subsequently proceeding accordingly with his thoughts, thereby personally mentally concluding that "the IVC was already IE-speaking by 1500 BC". Or something along that line.

It can happen sometimes.
