All income and expenses should be entered in the interview section, not on the form.

To enter your Schedule C income (and your home office info), first click Step-by-Step in the upper right-hand corner, then:

1.  Click Federal Taxes across the top.

2.  Click Wages & Income across the top.

3.  Click I’ll choose what I work on.

4.  Scroll down to Business Items.

5.  Click Start or Update by Business Income and Expenses (Sch C).

You'll get to the section where you can put in your home office info.  To see your forms after you've completed your input, click Forms in the upper right-hand corner.
