Regarding deductions and credit for F-1 student

Hello, I am trying to file my tax for 2021 through turbotax.

I am a non-resident alien, but did some stock trading with a bit of net loss; I have finished entering all the trades that I have done in 2021, so I should be good with that part.

For a bit of more context information, I have started my school in August of 2021. Thus, I have nothing do deal with the "third stimulus payment."

So I have entered 0 for the amount.

However, the turbotax is keep saying that I am eligible for $1,400 of Recovery Rebate Credit which I am not eligible since I am a foreigner.

What should do to file this correctly?

Moreover, I have checked that I have no deductions, but when I go to the summary, it keep says I have standard deduction, which I believe I have not selected and not eligible for because of my nationality.

Finally, I have no income in the state where I attend my university.

Do I still have to file state taxes?

Thank you for taking your time to answer my questions.
