What business tax return do you need to file? If you need to file a separate Business return like for a 1065 Partnership or LLC or a 1120 including a Single Member LLC - S corp or a 1041 Estate/Trust return you need Turbo Tax Business in addition to a personal tax program.
Or are you self employed, sole proprietor, Single Member LLC, Independent Contractor, etc? Those are filed on Schedule C in your personal 1040 return.
You might need Turbo Tax Business, 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,

You can have both a personal program and the Business program installed on the same computer at the same time.
