Thanks for the prompt reply, @ejohnson1481.

You can record the estimated taxes by writing a check. Writing and recording checks for your expenses keep your checking account organized in QuickBooks. 

Let me show you how.

1. Go to the +New icon and select Check.
2. Pick the Payee from the drop-down list.
3. Specify the Bank Account where the money will be withdrawn.
4. Complete the check fields.
5. Click Preview and print.
6. Choose Save and close or Save and new.

For detailed steps, kindly refer to this article: Create and record checks in QuickBooks Online.

Upon sharing the steps above, I would suggest consulting your accountant. This to ensure that you properly recorded the taxes and ensure your books are accurate. If you’re not affiliated with one, you can visit our ProAdvisor page, and we’ll help you find one from there.
