529s count as parental unprotected assets for factoring assistance. Parents are expected to contribute 5.64% of their unprotected assets annually for their kids college. You're also usually expected to contribute a minimum of 22% of your income ($17,600) and a maximum of 47% ($37,600).
Like Gin mentioned you probably won't get FAFSA, given you'd be expected to fork over close to $18k minimum plus a good chunk of what's probably in the 529. So unless she's going to a super-lux institute and didn't earn any scholarships, you're probably going to be paying the full cost.
Consider having the discussion now about colleges: how much you plan to help with $, what she wants to do in terms of a major, where she wants to go (local vs far), how she plans to get there in terms of $ (jobs, loans, scholarships, etc.). Last thing you want to do is let her become obsessed with QMU (Quarter Million $ University), not have taken the steps in high school to earn academic scholarships or working jobs in high school, and then become frustrated with you that the money isn't there to live that fantasy (or worse, ring up a 6-figure student debt and then bitch about it to you all throughout her 20s & 30s). That's probably the single best thing you can do and what 99% of parents never do with their kids until they've already received the acceptance letter.
