Why is reconcile not adding the payment amount on the left side?

Can you provide a pic of the Balances you inputted on the popup prior to this page as well. What Ending statement date, charges, Payments, and ending balance did you use?

Looking at this:

The main question here is how you got a credit of 388.45 for the Cleared balance (note the signs are reversed in a credit card account/reconcile). You should have a Cleared Balance of 4077.92 to be able to reconcile/balance.

The Cleared Balance is the total of all the reconciled transactions in the register plus the cleared transactions up to and including the statement ending date entered. I see that you are reconciling to past month. The first thing to make sure of is that you don't have any reconciled transactions after the end statement date. Quicken will include them (but not show them in the above dialog, because it only shows cleared and uncleared transactions there. I personally think this is wrong that they include these reconciled transactions, but that is what it does).

Past that here is what one should expect:

Notice how these two values are the same. By your image above Quicken has calculated a credit of 388.43 (the signs are reversed in the reconcile window) for your statement ending date.

See what happens when I put in a reconciled transactions for $100 charge past the statement ending date.

If that isn't the problem, then one of the past Reconciled/Cleared transactions has changed. My guess would be the Opening Balance of the register (the first transaction in the register). There is a long-standing bug that Quicken changes that statement at times.

Just to be clear. The charges total never includes the payment. The charges go into the list on the left, and any payments/refunds on the right.

The math is done in the background. And it is, the total of all the reconciled transactions (charges and payments/refunds) and the selected cleared charges/payments.

What is the balance in the credit card account on 2/28/2025?

Provided there isn't any uncleared transactions before 2//28/2025 (which will throw off the total) if it isn't 4077.92, then you have found the problem.

Now that you have included the 3/11/2025 payment here and it balances (without the 4,466.35) my guess would be that the 4,466.35 payment has been duplicated, and that you will find that the duplicate 4,466.35 transaction is marked reconciled (and that is why it doesn't show in this window).

If that is correct, then you just need to delete the duplicate 4,466.35 transaction.

The charge totals seem to be "within reason".

Your first screenshot had 49 and a total of 4077.92 and your second one has 103 and at total of 8600.29. So, about $4000 in each statement. But of course, without seeing the actual transactions I could be totally wrong.

Did you check the first statement in your account? The "duplicated reconciled transaction" could be that transaction where its value is has been changed to your statement balance amount.

Can you give a screenshot of the balance in the credit card account around 2/5/2025?
