529 Distribution deducting Room and Board

So I know Room and Board qualify for expenses for a 529 Distribution but don't know how to enter it? The 1099-Q has earnings in Box 2 as part of what we withdrew was used earmarked for Room and Board.  As a result my daughter is getting taxed on a portion in Box 2 when I step through the program .  I've seen others say you can just not enter it if your expenses exceed the distribution but is there in fact a place this can be entered so I have the applicable paperwork?
