Work related expenses for regular employees are not tax deductible. The program still allows you to enter them, because they may be deductible in some states if you itemize your deductions. There is a section on the deductions and credits page for work related expenses.
your employer may reimburse you for work related expenses tax free. If they don’t, I would stop buying work related supplies with your own money. Additionally, in some states it may be illegal for your employer to require you to pay out-of-pocket for necessary working expenses, especially if the effect of buying those supplies reduces your income below the minimum wage. You should check with your state labor laws on the rules for employers that require employees to pay for necessary expenses.
