If your husband only received a W-2 for his work last year, he can no longer claim employee expenses on his return, including any home office expenses. Unfortunately,
job-related expenses for employees are no longer deductible under the new
law. Please see the TurboTax FAQ "Can employees deduct any job-related expenses?"
below for more information.

But if he was self-employed -- an independent contractor -- for part of the year, he can still claim business expenses on your return, to offset his self-employment income.
Please see the TurboTax FAQ "Where do I enter my self-employment business expenses, like
home office, vehicle mileage, and supplies?" below for guidance.
