OP said NRD was 62 w/ NRD 3/1/25. Since he didn't receive his benefit as of 3/1/25, it must be actuarially adjusted to reflect the delayed payment. (This assumes he was not working in suspendable service after 3/1/25 and timely received a Suspension of Benefits Notice.) If he was terminated as of 3/1/25, or if he was active but didn't receive an SOBN, an actuarial increase is required. First you need to adjust the accrued benefit to reflect the delayed payments, then apply the lump sum factor at the age of distribution.
This has nothing to do with a DC plan, no idea what you are referring to with those comments.
