I had the same problem and finally found it by going to FILE>Preferences>1099's (on the left menu)>Company Preferences on the right top>then turning on 1099's. I had to do this with all of my companies, but they were all turned on before the update that included the new 1099 forms. Knowing exactly how quickbooks works, they changed your "ON" setting to "OFF" on purpose to get you to think it won't work in your version so you'd buy an upgrade.
Best of luck.
