RMD on a small amount in DBP

Hi

DB plan terminated and did all the distributions during 2026 and also paid the RMD based on account balance method.

Now, a small residue ($550) hit the account which is also subject to RMD. It is roughly $20.

I cannot remember if there was a de minimum amount that can be ignored? Actual distribution was 2.5M with RMD of 100k.

TIA

Is this a one-person plan?  Why would a "residue" be only partially distributed (at the next convenient date) for a terminated plan?

Owner only and hit the account 2 months after the distribution occured.

I would just pay it all out. Covers the RMD and isn’t a burden from a tax perspective.
