Purchased previous year tax to file download but when I enter the license code, it says invalid and only allows me to chose MAC, but I have Windows

If you purchased it from a store, you should return it.  If it was downloaded from the TurboTax website You should follow the directions in What's the TurboTax phone number?

When you call an AI that is moronic and not an AI at all. It is just a scripted bot with a very limited set of questions and answers it understands. Then you are on hold forever. So TurboTax clearly prefers to neglect customers to extract more profit. Failure.
