1) If filing for ITIN (1040NR) for the 1st time,
and reporting US ECI of $10 in the Other Income category,
which is better to fill $10 under:
i) 1h (Then write "Other Income" in the description column), or
ii) 8z (Then Attach Schedule 1) ?
2) Also, blanks for other columns or fill 0 all the way?
3) Home Address in 1040NR=US Mailing Address?
I have watched the tutorial in the classroom below, but the 1040NR got much more complicated, than that when uploaded.
