Whenever you have multiple entries that need cleared, I recommend entering a cutoff date of a few months earlier of the month you want to start with. You can either select  all of them at once or a month at a time by clicking the Verified column, and then clicking the Verify button in the upper right. Considering how many years you have, I would almost use the cutoff date for the year-end until you get to 2023.  Once you have verified them, save it in final. Then you can start doing the reconcile for the last few months.
