How to file a tax return for a small business depends on how your business is organized.
If your business is a sole proprietorship or a single-member LLC, these businesses should be filed on Schedule C (Form 1040) as part of your personal income tax return. As you have already filed your tax return, you would need to amend your tax return and include your business income and expenses. TurboTax Self-Employed (online) or TurboTax Home & Business would be the right choice to prepare and file that return.
If your
business is not a Schedule C business, for example, a corporation, partnership, or multi-member LLC, you would need TurboTax Business
(Windows Only) to prepare the appropriate tax return.
