Hello Aspirant,
Hope you are doing well. Your question is incomplete as you have not clearly stated which declaration forms are you talking about. Please mention which declaration form you are talking about so as to get accurate answers.
In any case whatsoever, if you have any doubt regarding carrying an extra document, always make it a point to carry them to avoid unnecessary hassles. Because, carrying some extra document wouldn't really hurt you but not carrying any required document might.
Hope this helps.
