@pk : Thank you for your response.
I entered USA on h-1b visa in mid 2019 and spent about six months in 2019. In 2020, I was in USA in January and February and a week of March, so about 70 days. I never worked or lived in USA before 2019. I am still working for same employer. Home country is India. My employer did withhold federal, state tax and FICA whole of 2020, same amount as if had I been physically present in USA. Tax year cycle of my home country is different and I may possibly have to pay taxes based on my global income in my home country, but it will happen later after March 2021, when I file returns in home country - but this is unclear to me at the moment. I am not married.
Thank you.
