1. Obviously the "estimated numbers" are not the actual numbers.
2. If there is a code E you must have entered selling expenses, which you did not otherwise mention in your question. How much were the selling expenses? Did you enter anything else that you haven't mentioned?
3. You must have entered something different from what you said in your question. Could you possibly have reversed the proceeds and basis?
The solution is to go back and very carefully review all of your entries related to the sale.
