paycheck issued in January for wrong amount and needs to be corrected along with CRA amounts

SOLVED

I work with Sage 50 Canadian Edition 2019.2

I have two paychecks that were posted in January with the wrong amounts.  CRA remittance was paid based on these wrong figures.  I need to correct in order to reconcile the account and do not know how to post the corrections.  I know how to "adjust" and/or "reverse" a paycheck through the payroll module, but it seems to create a duplicate entry and messes up the remittance figures. 

Can you please give me the correct and detailed steps for posting. 

Thanks.
