@DaveF1006 Thank you! Got it. I have used the deluxe version. But I have questions about how to report my 1042S form. Because my 1042S with income code 20 is based on the U.S-China tax treaty (Article 20 (c)), its income is untaxable with the tax rate is 0. I checked the IRS Publication 519, section 9 (Tax Treaty Benefits). So, in definition , is my 1042S still a taxable income but with the tax rate 0, which I need to report in my 1040? Or, should it be directly considered as the income exempt from U.S. tax under a treaty, which I don't need to report in my 1040?
