Let me walk you through how you manually add transactions to your account.
Here's how:
You'll need to open an account first.
Go to Bookkeeping and select Chart of accounts.
Find the account you want to review. If you're new to QuickBooks, select See your Chart of Accounts.
Choose Account history from the Action column. Reminder: Not every account lets you add transactions directly.
Then, add a transaction to the account.
At the very top of the list, select the Add journal entry, Add deposit or Add cheque ▼ dropdown. Tip: The menu can be hard to see - it's just above the most recent transaction. You can also press Ctrl + Alt + N.
