Are you using TurboTax CD/Download? If so it doesn't have the "Is your mailing address outside Canada?" question. But if you answered that you were a non-resident on the page that asked what province you are in, then it should allow you to enter a non-Canadian address.
You can use 000000000 for your spouse's SIN number. You can enter her income in Canadian dollars or say “YES” when it asks if her income was zero. If you don’t know what her income is, then you will need to say “NO” to the spousal amount.
If you would like to contact our phone support team, you can call them at 1-888-829-8608. Their hours are currently 9 AM to 6 PM EST (Toronto).
