I really appreciate all your help! I do know how undeposited funds works, it's where I put all cash and checks we receive in payment from customers.

Unfortunately, it sounds like there may not be a way to get this insurance refund check into undeposited funds as a "prompt" to add it to my next deposit. I guess I'll just have to remember it exists, and manually add it when I make the next deposit.

But thank you for all your efforts to help!
