Here's some additional tips:
The ability to take the home office deduction on Schedule C is not based on the net profit on Schedule C but can be considerably more arcane.
As the IRS says, "If the business deductions that are unrelated to the use of your home are greater than the gross income derived from the qualified business use of your home, then you cannot take a deduction for this qualified business use of your home." This means that even though the net profit as shown on Schedule C shows a positive number, form 8829 and its worksheet may show a negative number.
Since you are doing actual expenses, first look at line 8 in Part II of the 8829. Is it negative? That will be your first clue.
If you have the desktop software, the following will work...
Click on the number in the box on line 8. A magnifying glass should appear at the left edge of the box. Click on the magnifying glass, and TurboTax will open the "Form 8829 Worksheet". Look at line 9 in Part II on the worksheet - this should be where your line 8 on the 8829 came from. Then look at Part II and see if you can start to make sense of a negative income number for your home deduction.
If you have the Online software, then the form 8829 and the 8829 worksheet can be seen once you pay for the product. Go to the end (File) and take a look at the Print Center or the PDF before you actually file.
