Hello there, @Kristy28.

I appreciate you for getting back to us here in the Community. I can show you how to enter the payment information in QuickBooks Online.

You can go directly to the Pay Bills Online section to set up the information you need. You should have an option to enter the bank account details.

Here's how:

1. Sign in to your QuickBooks Online account.
2. Click + New ,then Pay Bills Online.
3. Choose the Bill Pay Online dashboard widget.
4. Go to the Expense tab, then press Pay Bills Online.
5. To set up a vendor with open bills, select Set up Bank Transfers within the same line as the Payee. (Note: To set up a vendor before there are open bills select Set up vendors for bank transfers. You'll need the account number for the vendor.)

6. 

7. Select Enter vendor's bank account info.
8. Press Next.
9. Enter the vendor's bank account information.
10. Hit Save.

Also, yes, you can create a new bill to pay using online bill pay. After entering the transaction, you can follow these steps to make payment:

1. Sign in to your QuickBooks Online account.
2. Click the + New option in the upper-left corner.
3. Hit Pay Bills Online.
4. Select the checkbox on the bills you want to pay, then Next.
5. Review the payment info. If you need to make any updates, select Edit details.

   Note: The Memo field will only appear on Paper Checks.

6. Select Submit payment to submit your scheduled payments.

However, using this process will not deduct the amount directly from your liability account. I recommend contacting Bill.com Support to verify if they support IRS payments and to further assist you with the process.

If they don't and you decide to pay taxes outside QuickBooks, you can record them manually in the system. I suggest following the detailed instructions in the Recording prior tax payments article.

I've attached an article you can use to learn about the option available in QuickBooks for paying taxes online, as well as how to file forms: Pay and file payroll taxes online.

Please let me know if you need anything else regarding managing payroll taxes. The Community and I will be here to help you.
