How does the accounting date on a Payment journal line get set?

We had a voucher come in with an accounting date of 1/31/2021 on the 'Invoice Information' screen. On the 'Payments' screen, we have an accounting date of 12/31/2020. When the payment posted to journals, the Accounts Payable and the Cash Distribution journals had an accounting date of 1/31/2021. My business partner wanted it to be 12/31/2020.

Does the date on the Invoice Information screen dictate the 'Accounting Date' for the Accounts Payable entries or is there something else that I'm not finding.
