EOS Rebel T8i camera isn’t turning on.

I have watched several youtube videos nothing has solved the problem, recently got a SD card for it and a new battery. It is still not turning on.

I'd suggest Canon for service.  Visit MyCanon to register and initiate a service or repair.  You will also receive an estimate.

i'm afraid stevet1 is pointing you in the right direction.The camera and lens being dropped is bad enough news. But the overheating issue just pushes things to the next level, and not in a good way. The T8i is capable of shooting good quality HD video but wasn't really designed for conttinuous video duty like Zoom conferencing or podcastng. The overheating may have stresed some electrical components or circuitry. And the shock of being dropped may have pushed the camera over the edge. Repairs costs will likely exceed the value of the camera.

Your money will probably be better spent on a more suitable, dedicated video camera if you're using it primarily for shooting video.

Does Best Buy repair cameras? Geek squad right?

Not that I'm aware of. And even most camera shops woudn't do onsite repairs of this type. There's just too much specialized equipment and training involved.
