Hello,
It is unlikely that you will be able to claim this expense:
To deduct workplace expenses, your total itemized deductions must exceed the standard deduction. You must also meet what’s called "the 2% floor." That is, the total of the expenses you deduct must be greater than 2% of your adjusted gross income, and you can deduct only the expenses over that amount.
