That doesn't affect your income. But if you have a home office you can take deductions on schedule A for it.
Enter employee Home Office under
Federal Taxes Tab
Deductions and Credits
Choose Jump to Full List -or I'll choose what I work on
Then scroll way down to Employment Expenses
Job-Related Expenses - Click the Start or Update button
You need to answer YES to both questions about regular and exclusive use.
But it is a Misc Deduction and only the amount OVER 2% of your AGI is deductible so it might not be worth putting it in, unless it's a lot. And then the total of ALL your itemized deductions has to be more than the standard deduction to get any benefit.
