I am trying to complete my husbands tax return and it wont accept his SIN?

Please select everything that is in the SIN box and delete it. Then re-type the SIN, making sure to use only numbers and no special characters or spaces. There should be total of 9 numbers. Ex: 123456789

my 2018 and 2019 versions will not accept my wife's social insurance number, retyped and retype and it won't accept

I'm having the same problem with my wife'social insurance number
