Error comes up but it is not. "The sum of box 52 and box 53 must equal the total capital gain or loss in box 21 of your T3 slip. Please review your imported data."
For the error on the T3 slip not balancing box 52+53 to equal box 21A, trying to enter the sum of 52+53 into box 53 (deleting 52) should fix the problem.
