If partnerships are pass-thru entities, then what are Form 1065 Lines 24 - 32 all about?

My understanding is that each partner reports the partnership's financial information, per agreed allocation, onto each of their personal tax returns.

 

However, I noticed Lines 24-32 on Form 1065 that ultimately render an "amount owed" (Line 31) or "overpayment" (Line 32) which is at the partnership level.

 

An explanation would be appreciated!
