The first thing I would recommend is that you not pressure her too much. You might push her away and right into the WTS's open arms.
The 2nd thing I might suggest, if you haven't tried this already, is to remind her that once she's baptized that's it. No changing her mind without consequences. Maybe you could tell her that you thought it was the truth when you were baptized, but since then you changed your mind. Now, you have to pretend to hang on just so your parents will talk to you.
If this seems to have an impact on her, you might ask her to consider just how great the Society truly is if it treats people this way. Point out that there's a difference between the way the Society presents itself (including how her father surely presents it) and how the Society really is. Explain that, to her father and others at the Hall, getting baptized is the right thing for her to do for them. But what if it's not the right thing for her?
Or you could talk about other things you learned between the time your were baptized and now, things that made you regret your decision. I would think those are the kinds of details she'll most likely identify with and understand as that's the point where she is at right now.
You could also try to point out that cults aren't so obvious in real life as they are on TV. All but the most extreme ones appear "normal" to the uninitiated. They make a point of appearing normal to potential recruits, like your daughter. She may not like it so much later when they show their real faces. That won't happen until they've got her, though.
You may find it a waste of time if you're trying to convince her to leave the KH through scripture. Instead, focus on what the Society does, the kinds of attitudes it encourages (the world is evil, average Witnesses must obey and not question, etc.) and the harm its policies have done. Especially to you and people you know, or even better, people she knows. The Bible is arguable; concrete results are not.
At the very least, maybe these measures will convince her to wait a while more. Maybe she'll change.
