Get your taxes done using TurboTax

In the desktop version of TurboTax Deluxe, you can get to Schedule C from Forms mode or you can use Step by Step mode.    You can enter both business income and expenses in the desktop version, but not Online.   Online will prompt for an upgrade once you attempt to enter expenses.     Home Office expenses for the self-employed are entered with the Schedule C information.    

In the Desktop program, click on Federal Taxes, then Wages and Income, then scroll down to Business Items and click Start next to Business Income and Expenses (Sch C).
