Can I override and do a delete on the information that was input into the clergy residence section in error

Used CRA Data Base when filing. Was reviewing the Income Tax file before filing because there had been Warnings posted when I was inputing this persons' information , On review, even though I remember  inputing that this person had not changed residence during the 2018 taxation year,or during the previous year, the Clergy Residence portion was completed?   I am questioning if this has ever happened to someone else in the CRA database whose information was pre-filled and how does it get deleted?
