I have tried all of the steps (Backup/Copy/Restore, Validate/Super Validate, Set to Automatic Download). When I set the Account back to Manual Download, the Red Flag reappers, and says I have 11 Transactions to Review. I have had this problem for more than a year at least. It could be correct data somewhere, but I don't know how to locate and delete the corrupt transactions.
Thank you for taking the time to visit the Community, however, since this is an older post that was originally created back in June of 2021, it is less likely to receive an answer now.
I would suggest creating a new post for better visibility and to potentially receive responses from other users who may currently be experiencing the same problem. Doing so will also assist us with better tracking ability in the event that this issue may result in an escalation being required.
Please be sure to include a description of the issue, any error messages as well as the version of Quicken you have currently running (Help > About Quicken). The more information you are able to provide will help the Community to better understand and assist.
