Can I cancel an order charged to my credit card?

I paid for Turbo Tax 2020. I downloaded it. My MacBook Air says,"You can't open the application Turbo Tax_2020.exe because Microsoft Windows applications are not supported on MacOS." I finally completed my tax returns by signing in to Turbo Tax and having Turbo Tax it charge me at the end of the process.  I have now paid twice for Turbo Tax 2020.  I want to cancel the downloaded order that my MacBook does not support .
