I received a 1099-MISC from my employer with just one box (3) for $980. It also says MISC-A TRN. This does not look like the 1099-MISC form on TurboTax. What do I do?

The only other information on this form is an account number, a section that says COPY B For Recipient/Transferor and a Taxpayer ID Number which is my social. I am not self-employed, this comes from an employer in which I have already input the information from my W2. I do not know the reason for this form.
