The rule is that a CTR must be filed when cash transactions of more than $10,000 are completed by or on behalf of a person.
Once it's determine that a CTR must be filed, you need to include all of the cash transactions in or out conducted by or on behalf of that person (those persons).
And, if a transaction is included in a CTR, the conductor (when known) and each person on whose behalf the transaction was completed must be identified.
Jane is a person on whose behalf the $1,500 cash deposit was made. That deposit is included in the CTR because it's one of the transactions conducted by John, who completed cash-in transactions totaling $10.500.
Therefore, a part one section for Jane must be included in the CTR.
