If a participant has a FSA carryover, but quits before they have used their funds, is that money then forfeited? Or will the terminated participant still have a run-out period to submit receipts for date-of-service up to their termination date?

If year-to-date contributions exceed the amount of reimbursements and there is a remaining balance, the employee has a COBRA election available for the remainder of the plan year. If they do not elect COBRA, then expenses can only be submitted up to the end of their termination run-out period after which and funds remaining would be forfeited.

If an employer has adopted the Carryover, must a participant have a new-plan-year FSA for the prior year’s balance to carryover?

No. Any funds remaining in an individual’s current plan year FSA will be automatically rolled into the new plan year even if the employee didn’t elect to participate in a new plan year FSA. The participant now has the chance to spend up to $500 of his/her carryover money on out-of-pocket healthcare expenses in the following year.
