In-App-Purchases (IAP) are found in the Shop under the Options Tab.
Not all IAP are visible from the start.
Buying either the Lava Mace or the Lava Scythe will reveal the Lava Dagger and the Lava Claw.
Similarly, buying a 25x, 50x or 100x CpS or Souls Bonus will reveal the 250x and 500x CpS and Souls Bonus IAP.
Remove Ads is tied to your Steam/Apple/Google Account, which is why Remove Ads does not transfer between platforms.
All other IAP are tied to your save file and will transfer properly.
IAP on Steam
The Steam version has No Ads by default, which is why the mobile version is free but Steam is not.
While you can't buy IAP directly on steam, you can buy them indirectly.
Simply make the purchase on a mobile device, which will link them to your save file.
Switching back to Steam afterwards will have you bring the IAP with you.
