How do you write off a stale dated payment made by my company to a "supplier" ?

An insurance co. makes automatic withdrawals from my bank every month. I entered this debit to my banover a yeark on Dec 31, 2023, however, when rebalancing my account, the insurance co. did not make the withdrawal for that date. This uncleared payment has been in my books for over a year. How do I write it off?
