Go to Employees --> View. If PTO is enabled (Settings --> PTO to enable it) you will see a PTO button for the employee. Click the PTO button and you'll be taken to the PTO section where you can view PTO types, balances, and transactions. You can also add entries to the employee by selecting +Add PTO Accrual Entry.
If you would like to download the transactions, click on "View" next to the type. You then have downloadable options for PDF & CSV.
