Thanks a lot for the reply!
I do have a non-zero income on Box 2 (Gross income), although Box 6 (Net income) is blank.
Box 7a (Federal tax withheld) is non-zero and equal to Box 10 above, and Box 11 (Tax paid by withholding agent (amounts not withheld)) is 0. In this case, can I still follow your suggestion in the first part of your answer?
As for the second part of your answer, what do you mean by "To report the US tax paid (if you paid tax)"? Do you mean if I already filed taxes for 2021? If so, no, I haven't filed taxes yet. Then, I guess the second part of your answer is not relevant for me?
