Thanks for posting in the QuickBooks Community. I would love to hear more about your school project! In the meantime, I'm happy to help get you going. You can add a bank account to your Chart of accounts and use that for bank deposits. It doesn’t have to be an active account, since all you’re doing is recording transactions, not actually moving money. To add a bank account:
Click Settings (gear icon in the upper right corner)
Under YOUR COMPANY, select Chart of accounts
Enter the information and Save and Close
Once this account is set up, you can use it to make deposits. To make a deposit:
Select +New (upper left corner)
Under OTHER, select Bank deposit
Use the drop-down arrow to choose the bank account
Select the payments to include
Click Save and close
Here is a link to our QuickBooks Tutorials page Tutorials. There’s a TON of great info there.
You’ve got this. I feel an “A” coming your way. I’ll be around to help! Just comment below if you have any other questions.
