@dongauthier You will have to contact the CRA and double check that the information they have on file for your daughter is the same as what you are entering. They may still request that you mail in the return.
If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency
