Thanks @jagrover , I will try to do as you said with writing notes to make everything clear.
@DaveF1006 The $406 tax credit is my refund from the previous year 2020, that I decided to be applied to my 2021 tax instead of refunding me directly. I could file as resident for the whole year, but then I would have to report my foreign income for the time after I left the US, which I think is more complicated than dual-status.
