I have paid an employee gross for February (her start month) and March.I am paying her for April with qbo . How can I now get qbo to include the first 2 months?

It's a pleasure to have you here in the Community today, Stanley. Let me share details about adding payroll history inside QuickBooks Online (QBO).

In QBO, you can only enter or add historical payroll data if you haven't entered any paychecks. If you've already created paychecks in QuickBooks, you'll need to contact our Payroll Live Support team for assistance. They will be able to help you accomplish this.

Here's how:

1. In your company, click the Help icon in the upper right to display the support window.
2. You can utilize the QB Assistant by typing in your question or topic, which will provide options to help you obtain answers. Alternatively, use the Search tab to enter a keyword or topic of interest.
3. If you can’t find the answers to your questions, click on Contact Us to connect with an expert who can assist you further.
4. On the "How would you like to connect with us?" page, choose either Have us call you or Chat with us.

To check their support hours, please refer to this article: Contact Payroll Support.
