If you have chosen to prepare a coupled return (both spouse's returns prepared at the same time), two returns will be generated. Once you have completed all of the steps to file your return (reviewed warnings, confirmed your SIN, etc.) your spouse's return will come up for review as well.

If you are unable to locate your spouse's return, please contact our support team for further assistance.
