Urgent ChaCha tax question?

I am married, and I am unemployed. I stay at home with my children. In March or 2009 I started working for ChaCha online as an independant contractor. I already filed my taxes, (married filing jointly) with my husbands W2 from his job. I totally forgot about my working at ChaCha. I onlly made like $160 total from them. I am worried that our tax return will get denied or something and my husband just lost his job, so I am relying on that money. Does anyone know if I had to report that or what I should do? THANKS
