Hi there, octoberfermen. Let's find out why your payroll tax payment isn't in the check register.
 

May I know where you made your tax payment? When recording the tax payment and it's listed, you need to click Mark as paid. However, if it isn't, record it under Record tax payments (prior tax history).
 

I would also like to know if you've encountered an error message when you tried to create and file a 941 form. It's possible that there's a pending tax payment if you see an error.
 

Regarding the payment that doesn't show on the check register, it could be that the payroll payment isn't cleared yet by the bank.
