How do i report 529 distributions

I took distribution of 30k from 529 plan in 2019. This  entire amount was used for qualified expenses within 2019 and I have the receipts. (~12k tuition, ~12k room/board + misc/others) 

 

Now the college sent me 1098-T which has only ~11k in Box1. 

 

I am not able to tell what 1098-T covers and which other expenses i need to add manually. Any guidance?
