Thanks for your input, cparke3. I am not in U.S right now, and I do not have 1099 paper on hand to help preparing this return. If I HAVE TO file then I will need fly back to the U.S. I do not really care the Tax refund as long as I do not owe any money. I would like to know base on the information I provided above do I MUST file tax return for 2018 ?
Thanks again
