Is my Q2 recommended estimated tax payment including my unpaid Q1 estimated tax payment? It seems very high, I did not make that much more money in Q2 than Q1. I assume this is the case because the due date for Q1 has been pushed back?

I appreciate you for providing in-depth details of your estimated tax payment concern, jade-lui.

In QuickBooks Self-Employed (QBSE), it will provide you a breakdown of the estimated tax payments per quarter (as shown in the screenshot below). Let's make sure we selected the specific quarter that we need to pay on the Taxes page. Then, fill out the needed information and click Continue to accomplish. This is to ensure that we will pay for the right quarter.

For more tips and details about this one, check out this article: Pay Federal Estimated Quarterly Taxes.

To verify the estimated tax amounts per quarter, I'd suggest contacting our QBSE Customer Support Team. They'll pull up your account in a secure environment. Then, they'll help you review and check on why the amounts are too hight for the second quarter.

Just refer to this article to reach out to them: Contact QuickBooks Self-Employed Support.
