Filling in forms using multiple formats (Electronic and pen)

[OrangeMapleIsHome]

Hi, just curious if filling in some boxes using pen is an issue if the forms have already been printed after being filled in electronically? Just need to add (N/A) to some boxes that I forgot.

Thanks for any help

To add to this, in the complete guide, it states that "You must fill out all sections, unless instructed otherwise. If a section doesn’t apply to you, you must write “Not applicable” or “N/A” in this section. " Does this mean, that even if a box is not starred, you must put (N/A) in it?
