TurboTax has no 2020 $80 package for "Business" software, and not for "Home & Business" either:

_________________________________
I see that Amazon is, however, selling a download for 2020 "Home & Business" for $80, right now ......maybe that is what you are talking about. But that is the Amazon reduced price and not directly from the TTX store.
The H&B version contains both Self-Employment tax preparation (schedule C), and the Personal tax forms, so you don't need a separate purchase for both....(nor can you install H&B and (Basic or Deluxe or Premier ) on the same computer ).
If you did buy directly from TT then you must be an advantage member ... so you can get a refund of the unwanted program then either cancel or update your account for next year so this will not happen again.
First, here's to stop or adjust your Advantage membership (annual subscription):

And here's an online refund request form. Submit it within 60 days of having received your product.
