Get last AOC credit in daughter's college graduation year on her tax return. Tuition + expenses paid with 529 funds

My wife and I divorced and neither of us is eligable to get the last (4th) year of the AOC credit.  My daughter just graduated and I hoped she could claim it.   We paid her tuition for 2019 Spring in December of 2018 using almost all 529 funds.  So the 1099Q only came for 2018.  Since we can't double dip, I wanted to have my daughter pay the excess contributions on the $4000 she would need in order to get the AOC.  Since she only recently started working, I figured the benefit of the AOC would outweigh the extra tax she would have to pay.  Quicken asks me if I received a 1099Q, but I did not for 2019.  How can I get the portion of 529 earnings needed so that I can properly calculate the taxable portion of the distribution? The 1099Q from 2018 shows all the distributions for the year.  Only a portion of that was used to pay the 2019 spring tuition.
