The check I am concerned with involves online banking. From what you have said, I assume that the date that the bank mails the check, which I told them to write a week earlier, is the date for the deduction. In your example, if I told them on December 27, 2023, to pay a charity, and they said they would write the check a week later, I could not take that deduction till 2024, since my saying to pay it is not the "mailbox." Am I thinking correctly?
