I am using version R53.16 Quicken Deluxe in Windows. I have a problem in 1 Vanguard IRA brokerage account where I have 2 interest income amounts showing of $9.75 both on 8/31/2023 which does not belong in that account and doesn't appear to be from a different account. And in that same account, I am missing 2 reinvestment of dividend transactions. One is from 12/16/2022 for $150.48 and the other is from 6/16/2023 for $144.80. I tried to update the file by downloading the transactions from that period from Vanguard and open it to get Quicken to get the correct transactions. Quicken responded with "There are no new transactions." This seems to imply that Quicken has those transactions but is corrupting them as interest income transactions. Why would it do that? Is there a way to fix? If I delete the bad ones and rerun the Vanguard data file, will that hurt or help? Or do I delete the bad ones and just input the good ones? I note that my Quicken data file is very large at 146,531kb.
I found that a backup prior to 8/31/2023 had the correct transactions in that account. However, there are too many transactions since that backup to deal with if I use that backup as a starting point. A backup from a date after 8/31/2023 has the problem.
