Yes, it is innate, with a high degree of heritability. No one questions physical traits are innate, but some how when it comes to IQ it become highly contested...
You are using the word "heritable" as evidence for the "innateness" of a trait. "Innate" can mean multiple things, but the implication here is that it implies genetic determinism. Heritability statistics do not establish genetic determinism and, for intelligence, there's now substantial evidence in the other direction.
Trying to quantify genetics and intelligence is fraught because of history and ethics. We cannot put one twin in a box of food and water and the other in schools of varying quality. We also cannot clone Einstein and put them in various schools then test them.
Everyone has to live and grow within unjust societies. Some groups will suffer from racism, others may benefit. So it's going to be hard to prove much of anything without a lot of twins and decades of natural experiments.
The eugenics movements and Nazi experiments have also made the whole subject taboo.
Finally IQ is quite arbitrary and the tests evolve over time too.
