Hello @bikrant , I looked at the article you referred --- and also USCIS plus Title 8 which covers the operation and laws surrounding DHS . There is no such requirement for Green Card holders and there is no place on form 1040 for such entry. Therefore I have to assume that the article author misunderstood or confused requirements of form 1040 and 1040-NR ( cannot be filed through TurboTax and is ONLY for Non-Resident Aliens ).
Suggest you file your form normally , since you are a Green Card Holder ( and therefore taxed on world income) and present in the USA.
