That's not evidence against mis-delivery. When a refund check isn't cashed, it ages out. It sits on the Individual Master File as a credit. If a new address pops up on that account, a new refund check will be sent out. The interest still stopped back when the first refund was posted.'Mis-delivery' was our guess until we got it. The address printed on the check was the new one, which was effective as of July 2022...the check itself was dated 06/23/2023.
p.s... FJB.
