@cchanin Sorry no. The Business program is only available for Windows computers, not Mac. And also you can't upgrade to Business. Business is a separate program from the personal versions.
To prepare a 1041 return, you need to buy Turbo Tax Business Desktop program, not to be confused with the personal Home & Business version. Home & Business is just for personal returns that need schedule C for self employment. TT Business is not available to do online or on a Mac. You can buy the Windows Desktop program here,
