Do I have to pay taxes on travel reimbursement paid to me by my employer?

I worked for an employer in 2017 who offered to pay for my travel, hotel and conference registration expenses to represent them as a conference speaker. I submitted my receipts back in June, and my employer reimbursed me in full.

Then I received a 1099-MISC for the $1,060 they reimbursed me. I may not be understanding this correctly, but why did I receive a 1099-MISC? Isn't that for income? This was not income; this was a travel reimbursement.

Did I understand this paperwork incorrectly last summer, or did they do the paperwork wrong?


Thank you
