How can I correct the 1099 I downloaded from my stockbroker that is missing the basis from an uncovered stock showing a big loss that they sold for me.?

This was a restricted stock that I purchased in 2004 through a private placement. When the shares were released last summer I gave the stock to my broker. They did not ask me  for the basis.

Since this is a non-covered stock, the broker did not have records on the basis and were not required to keep records on the basis.   You will put your own basis information in.  You should first try contacting your financial institution to see if they have record of your cost basis, but simply omitted it from this form due to IRS regulations. For most stocks and bonds you can find your basis on the purchase confirmation slips, brokerage statements, or the Form 1099-B statement you received from your broker. For ISO sales and ESPP purchases, you may receive Form 3921 and Form 3922, respectively, which report purchase cost .
