As you enter data the first time, the program will walk you through each set of field data options such as earnings, retirement accounts, special receipts, and so forth. As you proceed you will have the option of dismissing or ignoring for now certain fields that may not be relevant. For each adult the primary field groups are shown in the first image: 
If any of the fields have been "dismissed" you can restore them by selecting the name of the person and clicking on the restore link.
