Hi there: I just sent back the CP09 that the IRS sent me a couple weeks later. I didn't file an amend... after googling for advice, I found some info saying that if you send back the CP09 you don't have to file an amended return. Of course, now I'm searching for the website where I read that just to verify, I can't find it anywhere! But I have a feeling it might have been on the H&R Block forum...
