Hi there, @kelly182. Thanks for specifying the reason why you're unable to finish your payroll history.
You can edit the difference in the amount you paid for the vacation item in your pay history by going to the Payroll section and then the Overview tab, as long as you haven't created any paychecks.

This section allows you to return to the setup and pay history tasks. However, if you've already created paychecks, contact us to make changes to your pay history.
Let us know if you have additional questions by leaving a reply below.
