I get a 1099-Misc for sales commissions though I'm not in business.

I am receiving a 1099 Misc for sales commissions from sales I made when in business years ago.  I sold my business and retired in 2010.  I am no longer in business of any kind.  When I put the info into Turbo Tax Deluxe it puts it into the business area.  What can I do to make this appear as just personal misc income?  I don't want to pay self-employment tax when I'm no longer in business!  Thanks!
