Hi there slhiltz,
It's vital that all your transactions be entered correctly for your tax filings to be accurate. QuickBooks Online is a great tool able to help you keep track of amounts of taxes on transactions so you can have the correct amount to file with the government. I can point you in the right direction for how to enter your installment payments so they appear in your filing:
In order for your tax installments to affect your filing, they would need to be entered following these steps:
- Click the Taxes tab on the left navigation menu.
- Select Sales tax at the top of the page.
- Click New, then select Installment.
- Enter the account the payment is from, the payment date, the filing date, and the amount.
- Click Record installment.
