Taking 529 withdrawals for a full time student who was a dependent for 5 months

My son was a full time student in NY for 5 months and took a job in June.  So he was a dependent till May and not after that.  We withdrew from his NY state 529 account for the Spring 2018 semester expenses.   I need to reconcile that qualified withdrawal with the 1098-T from his school.  Since he was was not a dependent for the whole year, his worksheet disappears from Turbotax.  How do I account for the qualified 529 expenses in my tax form?

 

Thanks
