Suggestions will generate to inform you of basic information regarding a specific return: potential issues, court cases, publication information, etc. Typically Suggestions are optional; however, it is up to you to read them and determine if the information we are providing needs to be completed.
A Suggestion will also generate for any entry made in an [Override] field. This does not mean that the override must be removed; it's just provided as a tool to help you track down any overrides of the program's automatic calculation.
