Just using James' Shortcut to fill out the DS-230, and am a little stumped about one thing on here:

When I filled out the I-130, and wrote down all the places I had lived, I was new to the whole process, and decided that since I had just come back from visiting my husband in the US for 4 months, that I should include that as a previous "residence."
Now knowing a little more, I know that I didn't actually "reside" here, and that putting that down may have been a little foolish even, since I basically implied that I resided here, when I was just visiting.
Since I have my info straight now, should I just leave that out on the DS-230 and list only the places I actually resided in Canada? Or are they going to look at the I-130 form during my interview and ask why I had left that out on this form?

Thanks in advance for any advise

I think it should list locations of your permanent residences. If the short trips to USA are temporary, and you maintained your permanent residence elsewhere, than they need not be listed.

Just my two cents.
