Have you already filed your return?  Please respond to this thread for further assistance.

No I have not yet filed. The entry is now no longer high lighted and I can't undo it.

As long as you have not filed your tax return, you can revisit any section to make changes using the topic search feature in TurboTax Online. On the left-hand side go to Tax Tools>Tools >Topic Search or Topic List. Then type the section or form that you need to update in the search box and click Go.
