There is a super minimal wait for network.
So, you should concantrate on CPU & enq:TM contention waits.
For CPU, check the SQL ordered by CPU section.
For Enq TM waits; Enq TM waits are caused by missing Foreign Key (FK) index on the FK constraint columns in the Child tables. Check : Locking and Referential Integrity (Doc ID 33453.1) & Resolving Issues Where 'enq: TM - contention' Waits are Occurring (Doc ID 1905174.1)
