OldUser, the question is on the online form that our lawyer filled out and we are making sure is filled out correctly. The offline form has instructions to ignore that, but the online form does not say that anywhere so we were just making sure it's okay to leave it blank on the online form.
Also, I am aware the N-400 is filled out by the lawful permanent resident. My wife is filling out the form (she's the LPR, I'm the citizen spouse), but I had the VisaJourney account set up so I'm the one posting the question here. Sorry if any of the wording is odd because of that, and thanks for any help.
