Allow me to answer your question about posting transactions in the right register, DeeDee.

The new bank account for payroll can only be used for paychecks that are created after the changes. 

Please note that QuickBooks will process the Direct Deposit from your actual bank account even if the one in your Accounting Preferences may be a different one. This is why it's important to update the banking details whenever you make changes to Direct Deposit.  Details about this are discussed here: Change Your Accounting Preferences in QuickBooks Online Payroll.

To move the amount from your savings to the correct bank account, you can create a journal entry. Allow me to share these steps with you:

1. Click the + New button and select Journal Entry.
2. On the first line, select the account that the amount was originally recorded in (in this case, your savings account) from the Account field.
3. Enter the amount in the Debit column.
4. On the next line, select the account that the amount needs to be moved to (in this case, your new bank account for payroll) from the Account field.
5. Enter the same amount in the Credit column.
6. Type in a memo or description for the journal entry.
7. Click Save and close.

You can refer to this article for additional guidance on creating journal entries in QBO: Create Journal Entries in QuickBooks Online.
