@pk Oh, of course. feel free to take your time. I will wait for your guide, then.
(by the way, if I did not put any value to any of the ‘not applicable’ fields, like AMT and some of the itemized deduction items, then it finally tells me that it is non-taxable, but I am not sure whether I did correctly or not; I know that the final correct response should be non-taxable, by the IRS regulation, but not sure about detailed steps, because there is no option that I can mark “filed 1040-NR last year”)
