Since he left in June, he would not meet the substantial presence test and not be a resident alien. So he would not have o file a US tax return, if he had no income, or, if he had income until he left, file a 1040NR as married filing separately. So you can file as married filing separately as resident alien or as dual status alien, if you do not want to report income after you left the US. Since your spouse is a nonresident alien, you would write NRA in the filed for his ITIN/SSN. You cant do that in Turbotax, you would need to print the return and write that in by hand and file by regular mail.
