Okay----your question resembled a recent one from a "stray" user from Canada. What kind of business return are you wanting to prepare? Do you have an S-corps, C-corps, or multi-member partnership? If so, you need to use TurboTax Business software for that --- on a Windows computer. The only way to prepare a return for those kinds of business using online is to use "Live" Assisted or Full Service.

Desktop Business:

If you use the desktop software you can prepare and e-file more than one return.
You cannot use TT Business for your personal Form 1040. So you need the software for your individual personal 1040 as well. If you are preparing returns for family members, you can prepare and e-file up to five federal returns using desktop.

You can also purchase the desktop download from various retailers such as Costco, Amazon, Walmart, Best Buy, Staples, Sam’s Club, etc. etc. etc.
This link Where can I obtain authentic TurboTax software? has a list of authorized TurboTax resellers.
Since you have not explained what kind of business you are preparing a return for---it is not possible to tell which software you need. If you are self-employed and are just preparing a return for a sole proprietorship, then all of your self-employment income and other kinds of income go on the same Form 1040, using any version of the desktop software, or by using online Premium.
