Just a thought: did you perhaps do the autofill process twice? This would double the numbers in some way. But other slips you downloaded would also be doubled.?
If the CRA AutoFill feature is not performing properly, you will need to enter your T4A slip manually.
When you sign in to your CRA My Account, if the T4A slip is not reflecting the correct figures, you will need to contact the issuer of the slip or CRA to verify these figures.
