Ordinarily 1099-MISC box 7 non-employee compensation is considered self-employment income and entered on a schedule C.
However, the 1099-MISC form instructions say 'If you are not an employee but the amount in this box is not SE income (for example, it is income from a sporadic activity or a hobby), report it on Form 1040, line 21.
Select Less Common Income, Miscellaneous Income. Then select Other Reportable Income and enter the description and amount. Enter something like 'Professional award reported in box 7' or something similar.
You will see a warning not to enter a 1099-MISC. That is because it is usually self-employment income. But in your case, this is where it belongs. Delete the 1099-MISC if you have entered it elsewhere.
