You’re correct. It’s certainly sounds wrong and you’re probably entering something(s) incorrectly. 
if I’m reading this correctly there should be no impact on the tax from the 529s or education credits.  If so,  delete all the education info... start with the 1098ts and dependent worksheets that you have the correct result. Then work on the Qs...keep an eye on the refund monitor to see the entry(s) that are giving you trouble.
