You likely did not break the threshold to itemize deductions. You either receive an automatic standard deduction based on your filing status or you itemize your deductions if over that amount (where these local taxes and reimbursed expenses are claimed)
For single filers, the automatic standard deduction amount is $6,300 and married filing jointly is $12,600. This means that in order to itemize your deductions, you would have to exceed these amounts. In addition to that threshold, the unreimbursed employee expenses are subject to a separate limitation. The amount that can be claimed is over 2% of your adjusted gross income. If the total is under 2%, you receive no benefit.
FYI- additional items which are a part of your total itemized deductions include mortgage interest, personal property taxes and charitable contributions.
