pillito,
According to the 1042-S list of codes and exemptions, that is listed as "pensions, annuities, alimony, and/or insurance premiums" without any treaty exclusion. As a resident alien, you are generally responsible to pay US tax on your worldwide income unless there is some specific tax exemption such as a treaty.
So, I suggest some clarifications are in order:
a) More precisely, what was the source of the income that was reported on the 1042-S? If it was, indeed, code 15, then it was not "earned income" and would not qualify for foreign earned income exclusion.
b) If pension income, e.g. a retirement account withdrawal, were you at least 59 1/2 years old at the time of the withdrawal? If not, you may be subject to an additional 10% early withdrawal penalty unless you meet one of the execeptions in PUB 575.
c) On the 1042-S, what was the tax rate listed, if any, in box 3b? And was income tax withheld in box 7a?
