@Query3 as I pointed out you a resident for the whole year ( see my ref for residency start date ).
Thus you use Standard deduction and form 1040 ( supported by TurboTax.
Which country are you from -- some countries have specific non-taxability of student/trainee income.
On 1042-S , you have two options -- either the employer rescinds the 1042-S and issues you a W-2 ( a bit unlikely , especially if they have already issued/transmitted to the IRS ) OR
map the 1042-S boxes to W-2 entry in to the TurboTax.
Do you need help with this ? Also please answer which country you are from ?
I will circle back
