@JudyJY , based on your reply as to the number of days in the USA and your F-1 visa extension, I am confident that you are still with the exemption period i.e. your original exemption runs for the calendar years 2021 through end of 2025 unless your visa status is adjusted. Thus you are not counting days present leaving you as a Non-Resident Aline ( NRA ) and therefore immune from having to report receipt of monies from foreign person(s). No 3520 for you.
Also note that you are taxed on ONLY US sourced/ connected income and you file your return on form 1040-NR ( not supported by TurboTax ( but by the likes of SprinTax, or similar or tax professional or persons ref'd. by your foreign students support at you school ).
Is there more I can do for you ?
