I'm looking at the submissions status on Payroll for HMRC. Previously it has said submitted, today it says processing ? What have I done wrong ?

Hello Kelly-Communityl,

Welcome to the Community page, 

You will need to check your hmrc account to see if it shows as submitted if it has not then you will need to check everything is correct in Quickbooks like the AO ref and credentials for logging in a password reset may fix the issue as the password needs to be over 12 characters long.
