Nice to see you posting in the Community space, @info1381.
I'd be happy to guide you on how to check your payroll journal posting in QuickBooks Online (QBO).
Let's go to the Payroll Settings page to verify the default payroll accounts linked to your payroll transactions.
From there, you'll know how your employment allowance credit post.
For guidance in using the Advance Payroll in QBO, see this article: QuickBooks Online Advanced Payroll Hub.
If you have any other concerns or questions about payroll, let me know by commenting below. I'll be here to help. Have a great day!
