If for business returns you are referring to the Schedule C that is completed by someone who is a self-employed independent contractor, sole proprietor or single member LLC that has not incorporated, then the answer is Yes you can use the Self-Employed edition. Schedule C is not a separate business tax return but is included with and part of your personal tax return, Form 1040.
However, if you are referring to business tax returns such as a Form 1065 for Partnerships and multi-member LLC's, Form 1120S for S Corporations, Form 1120 for C Corporations, then the Self-Employed edition cannot be used.
For those business tax returns you would have to use the the TurboTax Business Edition. The Business Edition can only be installed on a Windows based personal computer, not on a Mac or online. The Business Edition cannot be used to complete a personal tax return, Form 1040.
