Employee reimbursements under non-accountable plan should be reported as wages on a W-2.
This answer then assumes that you are an independent contractor. You're probably right that the payer should not have reported this, if you did not account to them with receipts, etc.
According to the IRS,
"The following are some examples of payments to be reported in box 7 ... A fee paid to a nonemployee, including an independent contractor, or travel reimbursement for which the nonemployee did not account to the payer"
"If the contractor adequately accounts to you for reimbursed amounts, you do not have to report the amounts on an information return."
However, you can use the business expenses you paid to offset the income received by the 1099-MISC. Enter all expenses you paid regardless of reimbursement. It would be good if you had copies of the receipts for your own documentation.
Did this 1099-MISC have the reimbursement in Box 7?
To enter your business expenses:
· Type “Schedule C” in the Search box.
· Select the “Jump to” link.
· Select Add expenses for this work (or Edit and navigate down to Business Expenses).
If the reimbursement was on some other box of the 1099-MISC (possible box 3), your travel expenses and other work-related expenses will be reported on Form 2106 and carried automatically to other Itemized Deductions (mortgage interest, property taxes, state income tax, donations, etc.) on Schedule A.
This is distinct from being an independent contractor consultant paid on a 1099-MISC and filing a Schedule C for Self-Employment mentioned above
Job-related expenses are reported on Form 2106 (Employee Business Expenses).

· Union dues and expenses. However, you cannot deduct the portion of the fees that pays for sick, accident or death benefits or for a pension fund, even if the fees are required dues.
