Export finalized accidental

Welcome to the Community, @frank94. I'll make sure to guide you on how to export your payroll data.
 

If you use our Standalone Payroll Product, you can export your payroll transactions directly into QuickBooks Online.

Here's how:
 

1. Go to the Gear icon in the top right corner and select Payroll settings.
2. Click the Pencil icon next to Export.
3. Select Export transactions in the Export section.
4. A screen will appear informing you of the number of transactions and the type of transactions being exported.
5. Then select Export.
    

You can check this article for detailed steps and if you want to individually export your tax payments or paychecks, or re-export a transaction if needed. 
 

Just in case, you want to export reports, lists, and other data from QuickBooks Online. Here's an article for that: Export your data from QuickBooks Online.
