Hi there, @ seif69.
The amount will be an overpayment that will be applied to the next quarter.
You'll have to locate the tax payment on the transaction page then exclude it to edit the date. If the tax payment is downloaded from the bank, then you're unable to edit it.
If the tax payment for the second quarter is not yet recorded, you can enter it by adding a new transaction. Let me show you how.
1. Go to the Transactions menu and click Add Transaction.
2. Enter the details of the tax payments.
3. Select Business for Type and click Income under Category.
4. Click Save.
You can refer to these articles for more information about the tax calculation in QuickBooks:
I'll be around if you need anything else.
