Hi HTM1
When you open those payroll transactions what is the Payment Method listed? I would assume it wouldn't say Electronic. As those transactions haven't been marked as electronic they don't have the necessary payment information to be processed electronically hence the message. This is caused by some incorrectly set up linked accounts. You might want to review Setup>>Linked Accounts>>Payroll Accounts. I would make sure that you have set the Bank Account for Cash Payments and the Bank Account for Cheque Payments to not be the same as the Bank Account for Electronic Payments.
In terms of correcting those transactions that are already listed, the only thing I think you could do*, would be to hide the transactions from that window by updating the linked account involved. For example, create a new bank electronic clearing account in your accounts list (Accounts>>Accounts lists>>New - give the account a name, and number and set the account type to Bank). Once that account has been set up, go to Setup>>Linked Accounts>>Accounts and Banking and set the Bank Account for Electronic Payments to be that new bank account. This will hide the transactions from the Prepare Electronic Payments window as the system is looking for transactions that haven't been processed electronically. As this is a new account you would have no transactions thus the window is cleared.
*And do welcome other members of the Community that have other solutions to share them. It should be noted that I have assumed the transaction has been reported to the ATO through STP and thus wouldn't be able to be edited, only reversed.
