My T4E for Mat leave only has box 14 and 22 filled. But when I fill those in on here a warning pops up saying other boxes need to be filled to equal box 14. What do I do?

Which version of TurboTax are you using? Free, Standard, Premier, Self-Employed/Home & Business? Is it Online or is it the CD/Desktop edition? And what numbers do you have for box 14 and 22?

Just put the total from box 14 into box 15 - regular benefits. It doesn't much matter where it goes, the total is really what matters. TurboTax is just looking to get a total of the other boxes to match box 14.
