is there a way I can find out what the total processing fees were for a given year.

There are two ways to find your total QuickBooks processing fees, @kyawheeler

If you're using QuickBooks Online Payments, you can find your total fees directly within the Activity & Reports page in the Merchant Service Center. This page provides a summary of all processing fees for the chosen time period, which you can print or export.
 

1. Sign in to the Merchant Service Center.
2. Navigate to the Activity & Reports menu and select Fees.
3. Filter the Dates.
4. Lastly, run the report and view your total fees.
    

Another way is to run a Profit and Loss report. If you're using QuickBooks Self-Employed (QBSE), your fees will be included in the Profit and Loss Report under expenses.
 

1. Go to the Reports section on the left-hand menu in QuickBooks Self-Employed.
2. Select the Profit & Loss report.
3. Set the date range to the desired year.
4. Look in the Expenses section for the category: Transaction/processing fees.

Additional tip:  For some versions or regions, processing fees may be grouped under Other Business Expenses instead. If you don’t see a specific "Fees" category, click the amount next to Other Business Expenses to view detailed transactions.
