Using 6.14 x 10^-5 for Ka for benzoic acid, I obtained 47.8% ionization.

Using 6.5E-5 for Ka I obtained 48.77 which rounds to 48.8% ionization.

Do you still have a problem? If so, post your work and let me try to find the error. But since you apparently posted 68% and the data base said it was wrong, you might want to try 48.8.
