Note entirely. But under deductions and credits tab in the job related expenses section, work it through to see if you qualify to claim a home office for your W-2 employment. If you do, then you can deduct a percentage of your utilities for your employment use. That percentage will be based on what percentage of your house qualifies for the home office deduction, if you qualify for that at all. If you don't qualify for the home office deduction, then you can't claim any of your other utility expenses either.
