I filed my 2004 return in early April. Yesterday, I received an 1099-OID showing interest (block 2) of $2,000. The broker reports this is an additional form rather than a revision to the package sent in March. The form from the broker was dated 4/13 and the envelope was postmarked 4/15.

I have never filed an amended return but I guess I will have to. Right? I filed electronically using TurboTax, so what is the procedure for the change. And will I have to pay a penalty?

Also, do I have a legitimate complaint about the broker's late notice? They tell me they got the info from FannieMae late. The 1099 is for one bond I have held for a couple years. I have forty bonds with this broker and it never ocurred to me that I needed to check that I had 1099's for each bond. What is reasonable?
