@MagicBoo As Brenda said above, it’s likely that CRA will see the error and add the missing slip for you. You’ll see if they did when you get your Notice of Assessment (NOA). If they don’t add it, then you can use ReFile or CRA’s My Account to make changes to your return, as this FAQ says: https://turbotax.community.intuit.ca/community/tax-return-amendment/help/i-have-filed-my-tax-return-...
It’s unlikely you’ll be penalized. Even if you have to pay additional tax because of your T4A, the CRA doesn’t start charging interest until May 1st, so you have plenty of time to get this sorted out.
