Thanks for your quick response, let me be more clear. I used j1 visa as an intern working for a company from Oct. 2019 to Oct. 2020 without pay FICA tax, and in Oct. 2020, I transferred to a H1b visa at the same company and started to pay FICA tax till to the end of year. I stayed at US the whole time from Oct. 2019 to Dec. 2020. Below are the questions:
1) Should I file the tax-return 2020 as a NRA or RA?
2) I already bought turbotax software service, but it seems it can't figure out my situation after filling all the info, and it showed that I owed thousands dollar federal tax (I guess because the software can not understand that I don't need to pay FICA tax when using J1 visa), can i still use Turbotax service? if not, can I refund?
3) What are your advices to my case?
Thank you very much.
