voided check amount is showing up in deposits

@J-Ro  Most likely, somebody had reconciled the transaction you voided. That tends to throw a wrench in QB's brain as far as beginning balances go.

You can either unreconcile back to a point where the balance was still correct, or you can do a mini-reconciliation to get it back to the correct balance.

To ensure accurate reconciliation, uncheck the box in the cleared column for the voided check, J-Ro. Allow me to guide you through the process.

Unchecking the voided check will balance the amount of your account when you reconcile. Here's how:

1. Go to the Accountant menu, then select Chart of Accounts.
2. Locate the account that you want to reconcile.
3. Find the voided check.
4. Tick the box under the cleared column until it turns blank.
   

Once done, you can reconcile your account.

I appreciate your efforts in following NicoleAscencionS's answer, @J-Ro. Allow me to help you further so you can successfully reconcile your accounts in QuickBooks Desktop (QBDT).

Before anything else, could you please share the check date? This will help us see if you have reconciled in a previous period, which might explain why the voided check amount still shows up as a deposit.

In the meantime, you can go back to the period when the balance was still correct and unreconciled from today back to that prior month, as recommended by FishingForAnswers.

Follow the steps provided below to get a Previous Reconciliation report to review your past reconciliations.

Here's how:

1. Go to the Reports menu, then hover over Banking and choose Previous Reconciliation.
2. Select the reconciled account from the Account drop-down menu.
3. Choose the reconciliation period you want to review in the Statement Ending Date section.
4. Select Detailed or Both for the report type. We suggest Detailed if you need to fix a reconciliation.
5. Choose the transactions to include in the report:
   • Transactions cleared at the time of reconciliation: This shows only the transactions present at that time.
   • Transactions cleared plus any changes made: This displays the transactions at the time of reconciliation and their current status.
6. When you're ready to view the report, click Display.

@J-Ro 

When you voided the check, you must have selected "Yes" when asked if you wanted QB to create a journal entry (JE) to replace the original check and then a reversing entry (deposit) in the current period.  That is what gave you the deposit that you're seeing.  The deposit should be dated the same day you voided the check, but there should be another JE to offset that dated the same date as the original check.  Do you see that?  That's the offsetting entry to balance your reconciliation.
