How can I change the date for a transaction that was paid and post marked in 2023 but didn't record in QB until 2024?

Hello there, chelsey.

For me to be able to assist you appropriately, may I ask what type of transaction you're referring to? Providing me with this information will be very helpful in addressing your concern.
