If you come across a Red Alert, and see there is a question on that screen with "N/A" as a selection, the alert may be asking that you switch your "N/A" selection to "Yes" or "No" instead. Although the alert may not be directly related to any other information on the screen, you will, of course, want to verify all information entered to ensure it is correct.
Note. The option of selecting "N/A" is usually only used in the program if the information you previously entered within a particular section of the Q&A is no longer applicable to your return. If you still plan to include that information on your return, you would need to select either "Yes" or "No" to each question within that particular section.
