IIRC, the chief engineer for Curtiss had it worked out in late 39 or early 1940.
Yes, the P-40 was a somewhat dated airframe by the time the war was well underway. However, even underpowered and handicapped at high altitude, it performed admirably. A significant power increase combined with high altitude capability certainly would not have hurt it.
There was a whole lot more different about the P-63 compared to the P-39 than just the engine. And the P-39 SHOULD have been available WITH the turbocharger by 1940-41 AND seen the later improvements as well.
