@tamk236 from your response , what i get :
(a) your filing for 2022 ( covering your earnings for the period Sept. 2022 through 12/31/2022 should have been filed on form 1040-NR ( this is not supported by TurboTax , -- SprinTax, School Foreign Student grp. or a Tax professional would be able to do this). If you filed a form 1040 using TurboTax, your only choice is to amend this return.
(b) For the tax year 2023 covering your earnings from Jan1st. 2023 through the day you left USA can be filed on form 1040 ( supported by TurboTax ). Have you filed this return ? If you have then again you may have to do amended return. TurboTax on-line would certainly be available till Oct. 15th.
You can always download the forms required ( for 2022 ), fill out the correct information ( including updated SSN , the amounts withheld and/or amounts paid to the IRS etc. ), and turn in by mail to the IRS. Don't forget you also have to / file for the State.
For your J-1 work at Purdue did they not give a W-2 ? Or who was your employer that sent you the W-2C ?
I will come back once I hear from you .
