1099 Misc form , Please help

I checked my mail after i done my taxes and notice they sent my tax papers to me, in the papers it had a separate letter that reads misc 1099, need help.

 

Did i miss the chance to earn more money? please tell me. Because i didn't think i had to enter nothing in box 3 on my taxes, and i didn't get this form until after i filed my taxes. Also do i have to send this form to the IRS??????????
