help, think I need a amended 1040
I got a notice(form CP2000) from the IRS stating that I've errors on my 2007 return, the errors were:
1. 2006 state refund omitted. (my mistake, I switched tax software and didn't check my return thoroughly)
2. I made 3 stock trades in 2007 and didn't provide the transaction details in schedule D now the IRS uses zero as the cost basis so now I have a $9k capital gain(wouldn't that be nice !) I don't recall giving every transaction details in the past but then I've made very few trades so my memory is sparse.
after a little googling, it looks like I need to file a 1040x and a corrected 1040. Do I need to attach all documentations(W2, etc) as well? any other pointers? thanks.
