Adjustments necessary when employees take vacations

Hello QBO Community! 

I recently took on an Office Management role at my company, and I want to ensure how I was trained to adjust vacation time is correct. 

For each Employee --> Employee Details --> Pay --> 5) "Let's create a new vacation policy"  - there is a Make Adjustment options. 

Each time I am doing payroll, I go to this Make Adjustments, and deduct the respective hours and pay to those who took vacation in the timespan of payroll. 

I want to ensure this is the correct way to operate, as I noticed I can't find a history of adjustments made so I can't confirm the manual list I have of employees and time taken against the vacation time that was adjusted prior to me taking this role. 

I just want to ensure I am not negatively impacting payroll
