If this was a distribution and rollover of an IRA, this would have been reported on a 2023 Form 1099-R that is reportable on your 2023 tax return.
An IRA can also be moved by trustee-to-trustee transfer where the funds are sent directly to the new IRA without any payment being made to the IRA participant. A trustee-to-trustee transfer is neither a distribution nor a rollover and is not reportable.
