T3 Error stating box 52 & 53 must add up to box 21 and they do!!! I have checked and re entered this multiple times. I also have had these slips year after year.

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.

Thank you for choosing TurboTax.
