With the online version of TurboTax you can not edit the worksheets directly. YOu'll have to work through the SCH E section of the program again, until you come to the screen that asks for the number you want to change. After you change that number, you must continue working through that property all the way to the end, to ensure that your change is "in fact" saved and used to calculate your tax liability. In short, any changes you make are not saved until you get to a screen with a DONE button on it, and you click that DONE button.
Also take note, particularly for the CD version of the program, if you edit a worksheet with an over ride, two things will happen.
1) You may not be able to e-file the return. You will have to print, sign and mail it to the IRS (and your state if applicable).
2) You will invalidate the TurboTax 100% accuracy guarantee.
