I just received a 1099 that says I was paid for services rendered in 2009, which is wrong - these services were performed in 2010, just recently.

I have a bank copy of the cancelled check with their date (1/10/2010) and I have email correspondences of them saying they just mailed the check,.. on january 12, 2010 ..

I am sure i can prove I am right, but I do not want to get audited and HAVE to prove it..

How should I handle this?

thanks
Sam
