I have a 1099-Misc. the amount is listed in box 7. It should be included as other income line 21 on 1040 . How do I show this on line 21 other income on form 1040?

This 1099-misc is a result of a retiree contract for legal services from General Motors Legal Services plan Trust and does represent work related income.  It should be reported on Line 21 other income on 1040.  How do I report this correctly
