Dotting i and crossing t in 'tax credit'

Home Sale Hindsight

Q: How does one get information on what forms to fill out when buying a new home? It’s my understanding that a form needs to be completed within seven days after the close of a property. I was eligible last year and did not know I needed a form to complete and submit for a certificate.

So I have two questions:

1. Am I solely responsible to know the process, or does my agent have a responsibility to guide me through this?

2. Is there any way I can get this credit based on my purchase last year? I closed on March 15, 2009.
