@leezhengze , I am not sure I understand the situation --
1. Did you file a federal return for the year 2020, 2021?
2. If you filed a return which form did you use -- 1040 or 1040-NR
3. Which country are you from?
4. Am I to assume that you are still on F-1 original or an extended F-1
5. When did you enter this country with F-1 first ?
6. Was this your first entry into the USA ? If not with what visa did you enter before and how long did you stay ?
