You can get that FUTA payment into the system for the 1st quarter of 2018 using the instructions below:
Entering a Historical Tax Payment
- From QuickBooks Online, navigate to the Taxes tab and the Payroll Tax section.
- Select Enter Prior Tax History. Click Add Payment.
- Choose FUTA as the Tax Type, and be sure to select the Q1 2018 as the Liability Period.
- Enter 1/25/2019 as the Payment Date, add a Check Number or Notes if you'd like, and elaborate on the Tax Item Amounts below.
- Click OK.

With these steps, you can enter as many historical tax payments as you need for recording purposes in your QuickBooks Online company. Please let me know if there's anything else you need to succeed with QuickBooks. Thanks for bringing us your question and take care.
