Please see our TurboTax article: Claiming Child Care Expenses In Canada. Our software may not be allowing the claim on the spouse's return for different reasons. If you still need help, we believe your best option is to contact our telephone support team for further assistance, as they have the option to view your screen to help resolve the issue. To contact them, please follow this link: Contact Us. When asked if you wish to receive an email say NO then say "speak to a representative" then hold the line.
Thank you for choosing TurboTax.
