We switched from QB Desktop to QB Online for payroll. How do I ensure the previous pay periods are entered correctly for their W2s?

Good morning, @el_cutiger-yahoo. 

It's great to see a new face here in the Community. I appreciate you coming here with your question about payroll. 

If you're still having issues after reviewing this guide, set up a prior payroll for QuickBooks Online Payroll, then I recommend contacting our Customer Support Team for further assistance. They have a screen share tool to help walk you through some additional steps. Here's how: 

1. Go to the Help icon in the top right-hand corner. 
2. Click the Contact Us button. 
3. Give a brief description of the problem and hit Let's talk. 
4. Scroll down and choose to Get a callback. 

It's that easy! 

Keep us updated on how the call goes. I want to ensure that you get back to business. Have a wonderful day!
