is there a way to get a New Taxfilers tax to efile when the name sin and everything is entered exactly as the Service Canada Paperwork. but cra rejects it for efile

Hoping for a workaround.  The Canada Post problem doesn't help. 

This tax filer is a Canadian Citizen and under 18 living with parents and attending school.  So, CRA should have the information on her through the Child Tax Benefit I would think.
