I'll be sure to assist you in resolving the issue of the payroll item not showing up, sntfchf.
There could be a few reasons why some transactions may not be able to be matched with the existing records:
You can find other matches and confirm the correct date range on the Find other matches page.
Also, toggle the Automatic matching feature off and then back on again. This can sometimes trigger the system to re-scan for potential matches. If the problem continues, you'll have to match manually any new transactions.
In addition, I'm sharing an article that outlines the benefits of accurate record-keeping for businesses and employees.: Run payroll reports.
Feel free to reach out if you have any other questions about matching downloaded transactions in QuickBooks. I'm happy to provide further assistance whenever you need it.
