Hey turbotax I'm having the same issue ,efiled my return a couple of weeks ago got 4 more T3s may 8th, entered and tried to refile but getting the same error message about boxes 52 and 53 adding to box 21 redid the math at least a dozen times and even tried the fix of putting the total in box 53 only and also rounding up the amounts no luck. It says print and mail return or try later. Is this turbotax issue or CRA.
Signed frustrated.
