Yes, TurboTax does support the form 1040 for the time you were a resident alien. If you became a resident alien at the end of the year, you may not need to file a 1040 return depending on how much you earned. If you earned less than $14,600 and you are single, you would not have to file a return as that is less than your standard deduction.
You would still need to file a 1040NR for the time you were in the US prior to the date you became a US Resident which as stated above can be done through Sprintax.com
If you are not a U.S. citizen, you are considered a nonresident of the United States for U.S. tax purposes unless you meet one of two tests. You are a resident of the United States for tax purposes if you meet either the green card test or the substantial presence test for the calendar year (January 1 – December 31). TurboTax handles returns for US residents, only.
TurboTax does not handle non-resident tax returns (Form 1040-NR). Although TurboTax doesn't support IRS Form 1040-NR (U.S. Nonresident Alien Income Tax Return), we have partnered with Sprintax to offer both federal and state tax preparation for international students, scholars, and nonresident foreign professionals.
