New CERB Report TAX106CN - How do you update totals

Our year-end process uses manual checks to update the balance records. So for the pay period ending December 31, 2020 we may have an overpayment paid back to us for the period of March 31, 2020. According to the CERB rules we should be reporting the amount paid (original amount less adjustment) in code 57 of the T4 slip. I have tried a balance adjustment to move the balances back to March however it has no affect on the CERB reporting.

My question is, how do we adjust balances back to the proper pay period so it reflects correctly on the T4 slip?
