I believe you are working in the desktop TurboTax. If so, items marked in red means they need adjustment, either an amount has to be entered, changed or deleted. If you can't determine what is wrong, you may have to remove that form entry and re-enter it. There may by an option on the bottom of the form to delete it, otherwise you will have to go back to your Form 1099-R entry in the question and answer mode and delete it and re-enter it.
