Hi Danielle11,
Welcome to QuickBooks Community!
Firstly I would recommend checking if there is a circular arrow icon next to the payrun you finalised, which indicates that the journals have been posted in QuickBooks.
The payroll journals can be found from running a Journal Report in the Reports section - filter the report to show the date the pay run will be paid.
Alternatively, check the default accounts in Payroll against the QuickBooks Chart of Accounts account history. You can view the default accounts in Payroll Settings --> Chart of Accounts.
Let me know if you're able to find the journals after following the above steps.
