do not repeat reporting any of these items on both k-1's

 you can report as follows

line 5,9a,13,18  - either k-1

line 10 same k-1 as line 9a

line 13 need to know which lines a,b,c etc- any that are itemized deductions can go on either k-1 but others may have to go on a specific k-1 - you should have gotten details

line 17 this too may have to go on a specific k-1 - again details should have been provided

line 20 is just like line 13. some may need to go on a specific k-1 others may not even have to be entered.
