I am using Quicken Classic Premier for Windows, release R56.9, Build 27.1.56.9 on a Windows 11 laptop. I have been using Quicken for a very long time - my check book register goes back to January 1997. As soon as was feasible, I converted to the electronic downloads for updates and reconciliations. Up until a few months ago, there has never been an issue. Since January, I have had four "balance adjustments" on one of my Citibank cards because the reconciliation would not balance, and none of the charges matched the difference. And these adjustments are growing. The first was for 1.01 in January, in my favor. In February, there were two, 15.68 against me and 31.44 in my favor about two weeks later. Today, a huge difference against me in the amount of 542.05. Again, no charges on my statements (paper or on line) reflect these amounts, and none of the pending charges showing on the Citi website today, added together, don't even come to 20% of this amount.
What could be causing this? What do I need to check other than printing out four months of statements and manually checking everything? This is my primary spending card we use for everyday living, in order to earn the AA mileage.
Thanks for any advice you can pass my way.
