You can only deduct unreimbursed job-related expenses on your tax return. If you were reimbursed for the expenses by your employer, then you technically did not pay for those expenses because you received your money back.
And, the reimbursements are not included on your W-2 as income because you were simply being reimbursed for expenses that you paid for, not for work that you did.
So reimbursed expenses are not included in the 2106 form as they are not deductible. This is because you did not actually pay for those items, your employer did by reimbursing you for them.
