QuickBooks Solopreneur is designed for recording purposes only. When you record a payment in the app, it confirms that the payment has been made.
On top of that, the app does not automatically record these payments in the tax section, as it primarily focuses on calculating income and expenses for your business.
You can find this article helpful about reviewing and updating your tax profile in QuickBooks.
