You cannot apply for an ITIN through TurboTax unfortunately. You will have to file a Form W-7 separately to obtain the identification number.
As you cannot e-file your tax return without a SSN or ITIN, here are the steps how you submit your taxes and apply for ITIN simultaneously with TurboTax program:
-In the program, as you enter the information, leave the SSN space blank
-After entering all your information, print out returns and required forms ( write APPLIED in the SSN space)
-As TurboTax does not support the Form W-7, fill out the forms by following
https://www.irs.gov/Individuals/General-ITIN-Information and attach to other required documentation
-Submit everything including your tax forms to IRS Austin location in Texas. ( Form W-7 instructions)
