I am looking at my 1099-B as well as 3922. When I go step by step through turbotax to adjust the cost basis for the 15%, it does align with what was reported as income on my W-2. However, because of the stock splits since acquiring the shares, the Employee Stock Transaction Worksheet gives me an error because of the # of shares I sold vs. the # of shares purchased originally (pre-split). How do I go about amending this?
