I want to start over

I'd be glad to help you start over in QuickBooks Desktop, @Nick 102.

You can set up multiple company files. Instead of deleting, create a new file and start fresh.

Here's how: 

1. Open QuickBooks Desktop.
2. In the No Company Open window, select Create a new company.
3. Choose either Express Start or Start Setup if you want to get started right away, and then select Detailed Start if you want to do a complete setup.
4. Follow the onscreen steps to finish the setup.

Then, you can start recording and making bank deposits. Let me show you how: 

1. On the Homepage, select Record Deposits / Make Deposits.
2. In the Payments to Deposit window, choose the payments you want to combine and then click OK.
3. In the Make Deposits window, under the Deposit to dropdown menu, choose the account you want to put the deposit.
4. Check the deposit total. 
5. Enter the date you made the deposit at your bank.
6. Once done, click Save & Close.

I've also added this articles you can use to get started with QuickBooks Desktop: QuickBooks User Guide.

Post again if there's anything you need assistance with. I'm more than happy to help. Have a prosperous day.

Just create a new company file.

Navigate to File menu > New Company.
