This problem is a bit unrealistic, since it takes years to accelerate up to 0.98c (relative to the frame in which you're initially at rest) at the maximum comfortable acceleration. Still, I'll answer as if that weren't an issue. If from the daughter's point of view, the trip takes 33.75 years, you'll age only about 6.75 years, so she'll gain 27 years and end up the same age.
