Capital gain income from most investment sales from US sources would not be taxable to you if you are not a citizen or resident of the United States. Consequently, you could not offset your capital loss carryovers against non-taxable capital gain income, as it wouldn't be reportable on your tax return. If you are trying to preserve the capital loss carryover in case you may need it in the future, you may be able to file a form 1040NR to report the carryover amount only. We don't support that return at TurboTax so I can't comment on it, but you can read more about it in the instructions of Form 1040NR: Form 1040NR
