5500 Schedule C Question

Record-keeper provides a one-time payment to its TPA partners based on a new plan that comes over (based on asset size).  For example, in 2018, one new plan is placed with the record-keeper.  Based on the asset size, the one-time payment to the TPA totals $6,000.  It is paid out of the general assets of the record-keeper.  This amount is not paid by the plan, participants or investments held in the plan.  Does this need to be reported on the Schedule C of the Form 5500 as indirect compensation to the TPA?  Does this need to be reported on the 408(b)(2) disclosure?

Thank you!
