Thank you for sharing this to us, @gksteele6205 . When you void transactions from an earlier period, the system will revoke the check in the period it was originally issued, not in the period it was voided. This results in a discrepancy in your current period.

In your case, you'll want to enter a journal entry dated the same date as the original check.

Here's how:

1. Click + New, then select Journal entry.
2. On the first line, select the other account you're moving money to or from in the Account field. Depending on if you need to debit or credit the account on the first line, enter the same amount in the opposite column.
3. Check the amounts - you should have the same amount in the Credit column on one line and the Debit column on the other. This means the accounts are in balance.
4. Enter information in the memo section so you know why you made the journal entry.
5. Select Save and new or Save and close.

After that, Create journal entries in QuickBooks Online. Dated in the current period, reversing the entry above. It is also essential to create a deposit dated in the current period. 

When preparing for the upcoming bank reconciliation, ensure you clear the two journal entries mentioned earlier. To prevent similar issues in the future, it's advisable to consult your accountant before voiding your check.
