TurboTax Business (different from Home & Business) is for filing a tax return for a non-living non breathing separately taxable entity, such as a Partnership, Multi-member LLC, S-Corp, C-Corp, Trusts, and Estates. TurboTax Business can not be used to file a personal 1040 tax return of any type, because the program does not include any version of IRS Form 1040.
TurboTax business is for the windows operating system only. It is not available for MACs, and is not available as an online product.
With TurboTax business you can install it on any computer that you the purchaser of the program, personally own. You can e-file a maximum of 5 returns per e-mail address. After that, you can complete as many tax returns as desired. But after the 5th e-file, any additional returns have to be printed, signed as mailed to the IRS. This is not a TurboTax limit. This is an e-filing limit imposed by the IRS.
