Hmmm... Using the desktop product I entered 2 sales for 10 shares each at a price of $40 per share and used your numbers and had no problem. Why don't you detail every single element of what you're entering: all the line items entered on the 1099-B input forms, all the bits and pieces of your Form 3922 entries. Maybe it's an "online" issue and I'll have to ask some SuperUser that has an online account to try this.
