You bought the Xbox series version. Buy the Xbox one version instead. GTA Online is available for both versions.

I’ve used the hard drives for my Xbox one but when I bought the hard drive, it said it was compatible for the series s.

The game I bought in the Microsoft store on the Xbox one. I was trying to play it on my series s.

I bought the game as well. Also it says it's available to play on the Xbox one. Which is why I bought it.

I just bought a brand new Xbox One X, but when I go to the store, Flight Simulator and other Xbox Series X/S games say they are "not playable on this device" and I can't get Flight Simulator to install on my brand new Xbox One X because it says it's "not compatible". Very frustrating.

So you bought an Xbox One X and expected to be able to play an Xbox Series X game on it?

Why would a game made for an Xbox Series X work on an Xbox One X?

If you want to play Xbox Series X/S games I would take your brand new Xbox One X back to the store you bought it and see if they will take it back and you could try and buy an Xbox Series S (Series X consoles are very hard to find, but a Series S can be found fairly easilly)

I needed this link to check if the game you bought is the Xbox One version or the Xbox Series S/X version
