How to enter VALID Social Insurance Number for dependents? Turbo Tax will not accept my dependent's VALID SIN. Clearing the data and re-entering does not resolve.

Please make sure that when you are typing in the SIN numbers, that you are only using only numbers and no special characters or spaces. There should be total of 9 numbers. Ex: 123456789

If you are still unable to resolve this issue, please contact our phone support as they will be able to assist you further. This form will help you get the right number: https://support.turbotax.intuit.ca/contact/

I was only using numbers.  No special characters.
