At the beginning of this week, I synced Quicken with BOA and all was well. Since then, the account balance in that account's register became incorrect - $18K too high. I reconciled the account with a BOA statement on June 25 and the balance was correct for that date and back through the history of the account.
Now, I can look back through the account register and the balance is wrong back more than 5 years. I tried running reports to see if somehow a single erroneous transaction was the cause and the see if somehow parts of the account register had been duplicated but could find nothing, going back to the start of the account in the year 2000. I ran a report looking for all the deposits including all dates but it appears normal, too.
I restored a backup from last week. It shows the same incorrect register balance,
I assume this is some kind of an environment problem with just this account.
Any ideas?
