how to delete info in investment income area?

[RobertB4444]

Go back to the wages and income area of your federal return and scroll back down to 'Investment Income'.  Click 'Update' on the section where you entered the wrong information.  A list of the investments that you have already entered will be displayed there.  

Find the one you want to delete and then click the little down arrow on it.  At the bottom of that investment there's a little button that says 'edit' and next to that is a little trashcan.  Click the trashcan and the investment will be deleted.  Then you can enter it in the correct location.
