For people who are claiming to be knowledgeable, there are some things they are not telling you.
File an amended return.
Get form 1040 D, which is capital gains and losses, and you still use that form for stocks held less than 1 year. Schedule D will show you what information you need.
You should have a final statement for the year which is a list of all stocks bought and sold. All of the basis information should be in this statement, and these statements should be available on-line. You might need to go to a previous year's statement for some of the basis. If you don't have this statement, contact your brokerage and ask for it.
He does not need the amended return unless the loss is significant.
If the loss is significant, he wants to do the amended return to get taxes refunded. There is no other reason...except that it's a good way to communicate the info.
As I said above...the amended return gets sent to the address they want the response sent...along with the response form...with the "I disagree" box checked.
He needs form 8949 and schedule D. The stock purchase info goes on form 8949 and flows to schedule D.
He does not need to send any proof...statements etc...but I suppose he can if he wants.
I've handled this so many times I thought I'd try to help.
