Can 1099-MISC Box 7 income that is a bonus from a former employer paid after I left the company be reported on Line 21 instead of completing Schedules C and SE?

I was a full time employee at a company that sold its business to another company in March 2017 and I went to work full time for the company that purchased the business.  In December 2017, the company that sold the business (my former employer) paid me a pro-rated bonus for 2017 and then sent me a 1099-MISC with the bonus amount in Box 7 (in addition to a W-2 for the time that I was an employee).  I'm not self-employed and this was a one time award -- can I put this on Line 21 even though it was reported in Box 7 on the 1099-MISC?
