We were switched from Intuit Payroll to Quickbooks Payroll. I found out how to export the payroll taxes (as iif files)....but how do i export the payroll checks?

Hello there, @mrsriggssandwich.

Let me share information with you on how to export your payroll checks in Intuit Online Payroll.

Here's how:

1. From the Payday tab, click Export.
2. Choose the payroll checks you want to export.
3. Select Export. 

From there, the transferring of your data are now starting. Then, once you see a Congratulations message, close the window and verify if those checks are on your QuickBooks register. 

For more details about this process, see this article: Setup export of IOP data to QuickBooks Online (QBO).

Let me know in the comment section if you have other questions and concerns about QuickBooks. I'm just around to help. Have a great day.
