After you file

Neither Intuit nor TurboTax would send an email with that kind of information in it. Check who the email came from. If it’s from the CRA, you can contact them or check your My Account to see what info was changed. If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are somewhere else you can call 613-940-8495. Here are more ways to contact the CRA: https://www.canada.ca/en/revenue-agency/corporate/contact-information/telephone-numbers.html

If you suspect the email came from a scammer, you can contact the the Canadian Anti-Fraud Centre (CAFC) at 888-495-8501 or visit their website: http://www.antifraudcentre-centreantifraude.ca/index-eng.htm
