In the downloaded version of the software, in Formsview, that is a direct entry. You should be able to enter the amount directly. Please go back to EasyStep and answer Yes to the question - "were you a volunteer firefighter and/or a search and rescue volunteer?" and enter the amount there if you cannot enter it in forms.
In the online version, you have to enter the question and apply the amount directly in the "Profile" section, under "Other Credits & Deductions" page.
