You have me to help you pull up the total deposit you've made for last year, abeyta999.
We can run the Deposit Detail report. Let me guide you with these steps:
Click the Reports tab.
Enter and select Deposit Detail.
Select Last Calendar Year as the Reporting period.
Click Run report.
If you want to add or remove some information on the report, you can customize it. Here's an article as your guide: Customize reports in QuickBooks Online.
I'm just a post-away if you need help. Have a great day!
