Please go to Help > About Quicken and let us know what version you are running now.
When did you first see this problem? Was it before or after Mar. 4, when R39.17 was first released?
Previous to the current version, did you ever have R39.17 or R39.21 installed?
In the affected account, have you ever used the Paycheck Wizard to enter the split transfers in your paycheck?
Does the problem also affect the Account Balances Report?
If your answers are After Mar. 4, Yes ran R39.17 or R39.21, Yes have used Paycheck Wizard, and Yes affects Account Balances report, you have probably encountered the problem discussed here:
https://community.quicken.com/discussion/7909601/r39-17-r39-21-paycheck-corruption-edited/p1
If this is your problem, you should update to R39.23 or newer, which fixes this problem going forward.
Then you should back up your current data file in case you want to return to it and restore a backup from before you installed R39.17. This would be about March 4. Verify that the problem is no longer present in the restored backup.
If the problem is not present in the restored backup, you will have to keep the backup and re-enter any transactions you entered since then.
