My husband is a NRA. we are filing married but separate. He does not have a SSN nor wants one as he is not American. how do I complete this form?

He can get an ITIN instead of a SSN.

If he does not want to apply for an ITIN, you can prepare your "Married, Filing Separately" return as follows:

You can't prepare and print a tax return in TurboTax without an ITIN or SSN for you, your spouse and any dependents.

The work-around for this situation is to use "Dummy" SSN/ITINs for your dependents to prepare the return. You can use your own SSN/ITIN with different last numbers. 

Or use "305-44-0001, 0002, 0003 etc.", a dummy number we use for training.

This should allow you to get through the Smart Checks and Reviews and print your return for filing by mail. "Erase" or white-out the dummy SSN/ITINs and replace with "NRA".
