The Business Edition is used to complete and file a S Corp tax return, Form 1120S. The Business Edition cannot be used to complete a personal tax return, Form 1040. The Business Edition can only be installed on a Windows based personal computer, not on a Mac or online - https://turbotax.intuit.com/small-business-taxes/
For personal tax returns you will need to use either the online or desktop editions. If you use the online editions then you will need to use either the Premier or Self-Employed edition since those editions support entry of a Schedule K-1 from the S Corp. If you use the desktop CD/Download editions, then any of those editions can be used.
