how to manage a mixed 1099-Q

I was told previously that as long as all 529 distributions are "qualified" I don't even have to address the distribution in tax return since the distribution goes to the beneficiary.  That's how I did it last year.  This year, I made the mistake of taking out too much so I have to count the unqualified amounts as her taxable income.  When TT asks for the amount, do I have to put in the full amount to match the 1099-Q and then itemize all the educational deductions.  Or, can I just enter the amount that was "unqualified" and have it NOT match the 1099-Q.  The instructions within TT are not clear, and neither are the instructions on the IRS website.  THX
