My wife is outside canada and doesn't have a SIN but the system insists on getting a SIN and it doesn't let me to leave that field empty and proceed. what should I do?

To proceed with the SIN when your spouse is a non-resident and does not have valid SIN,

please enter it as "000 000 000". 

Also please do not enter "-", you need to leave space between three digits. After this SIN will be accepted.

Thank You for using TurboTax.
