Thanks for leading me to that page. So "Spouse First Name Middle Name Last Name - NRA" in the entry space below the filing status checkboxes. And, leave the spouse's first name & middle initial, spouse's last name, and spouse's SSN boxes all blank. I'm surprised no one in the immigration YouTube space has done a detailed video on this. The few who cover this are vague and not very practical. Before I found this discussion, I found very little detailed info on how to do this.
