I-751 form – put N/A in every box that doesn't apply?

[meadow2 0]

Hi, I am filling out the I-751 and the instructions are really specific about using N/A for questions that don't apply to you. But on the version of the form that you can fill out on your computer, it doesn't let you input N/A (doesn't recognize the slash). Do I have to handwrite N/A in every box that doesn't relate to me? For example I don't have a child so do I have to put N/A on every single box on the two pages of the form that relate to children? Or I don't use another name, so in 2.a. 2.b 2c 3a 3 b 3c do I have to put N/A to not leave anything blank? Seems a bit excessive. I called USCIS and the person on the phone suggested that I should do that (put N/A everywhere that doesn't apply) just to make sure it's not sent back as incomplete. Any thoughts much appreciated!

 

Here is the para on the instruction doc:

Answer all questions fully and accurately. If a question does not apply to you (for example, if you have never been
married and the question asks “Provide the name of your current spouse”), type or print “N/A,” unless otherwise
directed. If your answer to a question which requires a numeric response is zero or none (for example, “How many
children do you have” or “How many times have you departed the United States”), type or print “None,” unless
otherwise directed.
