Yes, you can file jointly with your spouse. Based on your information, since both of you stay in the US for more than 183 days in 2018, you both are considered as a resident for tax purposes.
Without your spouse's SSN, you will need to apply an ITIN for her and you won't be able to e-file. Basically, you file and apply for the ITIN together. Here is how you would do it:
- In the program, leave the SSN space blank
- After completing the return, print out the forms. Write APPLIED in the spouse's SSN space.
- As TurboTax does not support the Form W-7, fill out the forms by following W-7 and attach other required documentation
- Submit all forms and documents to the IRS Austin location in Texas. (see Form W-7 instructions)
