@yuruyucheng , when did you enter USA with F-1, which country are you from; did you have any earnings during 2020; are you married ( and if so is your spouse a US citizen/Resident ) ?
I was F1 phd from (2015-2017) and (2018-2023). From China. Yes, Research Assitance stipend every year. Not married.
@yuruyucheng so 2020 will be your first year filing as Resident Alien for Tax Purposes. TurboTax supports the form 1040 that you need. When you get your forms from the Univ. just tell TurboTax the form you have and enter that data into TurboTax. There should;d be no issue preparing the return and you can e-file. Also note that students from China are allowed to exclude US$5000 from taxation -- using form 8233 etc.
If you have already got the earnings forms from the school , then you are ready -- start using TubroTax and tell me if there is any specific issue you encounter
stay safe
