Hello, @kathrynhollis195. 

Please allow me to join the thread and help share information about about journal entry. After creating an payroll expense account, you'll need link it to the journal entry to match the bank transaction. Once done, you can start linking it to the payroll data. 

To accomplish this task, go to the Banking. Here’s how: 

1. Click on the Banking tab and then pick Banking. 
2. In the Bank and Credit Cards section, select the account you’re working on. 
3. Go to the For Review column and look for the transaction. 
4. Press the entry to open the complete details. 
5. Under Category assign it to the Payroll account 
6. Hit on the Add button. 

Here's a link with additional information on how to easily add and match journal entry to transactions from your online bank account.
