Here's how you can find all of your overrides. On the Tools menu select My Tax Data. A window will open that lists all the entries in your tax return. Any entry that was overridden will say Overridden in the Source column. You can click on the heading of the Source column to sort on that column, so that any Overridden entries will be together. If there are Details or Import entries at the top of the list after you sort it, scroll down to see if there are any Overridden entries after the Details and Import entries. The item in the My Tax Data list tells you the form and line number that has the override. You can click on an overridden item, then click the "Go To Form" button at the bottom of the list to go to the form that has the override.
You should remove all the overrides from your tax return. An override can cause the automatic calculations in TurboTax to break in unexpected ways, even in places that do not seem to be related to the override. An override prevents e-filing and cancels the TurboTax Accurate Calculations Guarantee.
