Hello,
The inability to efile a federal return with an NRA spouse who neither has nor requires an SSN or TIN is a limitation (or deficiency) of Turbo Tax software. There is no such limitation with Tax Act's online software, for example, in whose preliminary informational questionnaire there is a specific checkbox for NRA spouses who fall into this category. I've been efiling my federal returns with them from overseas for the last several years for this very reason. Good luck.
