After you file

I don't know what part I'm trying to change. The software didn't pull my wife's stuff from CRA in correctly because there was an issue with her CRA login. I went back to the re-file option and the return does show that we're married. I checked every field from the beginning and they are all correct but it still shows an incorrect amount owing. I know the amount owing is incorrect because after correcting the CRA login issue I began a new return which shows a different amount owing.
