    (e) A member's contributions toward the cost of early retirement without discount made under item (a)(4) of this Section shall not be refunded if the member has elected early retirement without discount under Section 16-133.2 and has begun to receive a retirement annuity under this Article calculated in accordance with that election.

interest, in any refund claimed by the member under Section 16-151.
        (3) The contributions shall be refunded to the
