Same answer I wrote for a different question, but it still applies:  It depends the status of the time (new, printed, posted) to know how to fix it.  Under Help - Knowledgebase you can search for answers:  See

I'm usually printed and need to somehow correct it the following pay period so I use negative hours (which Sage doesn't recommend).  See:  https://support.na.sage.com/selfservice/viewdocument.do?noCount=true&externalId=25831&sliceId=1&isLoadPublishedVer=&docType=kc&docTypeID=DT_Article&stateId=21290&cmd=displayKC&dialogID=894422&ViewedDocsListHelper=com.kanisa.apps.common.BaseViewedDocsListHelperImpl&openedFromSearchResults=true

If the amount should have been posted to a different job in a different tax jurisdiction (state or local), then negative hours can only be entered when there is enough positive pay so that it doesn't result in negative gross pay for any jurisdiction.  So I enter negative hours the same bad way it was done before, and then enter positive hours the way it should have been done.  It's not perfect for fringes, etc. but we're ok with that.
