Travel history requirement while living outside US

[dakalti 4]

5 years ago - mid-2013 to mid-2014 I was living outside the US and during this time traveled to several countries. 

4 years ago - mid-2014 - Immigrated to US and started living here

Now - late-2018 - filing N400 under "3 year rule"

 

Question -  For the travel outside US in the past 5 years question on N-400, how should I itemize my travel in this situation. 

Specifically how should I answer the question "Day you left the US" and "Day you returned to the US" in this scenario when I had not even immigrated to the US and as a result, the "Day you left US" and "Day you returned to US" is not applicable. 

 

Should I say:

Day you left the US: N/A

Day you returned to US: N/A

Did trip last 6 months or more: No

Countries you visited: Country A, Country B, Country C, Country D

Total days outside the US: 20 days

If filing under the 3-year rule, answer every question based on the past 3 years, not 5 years.
