How can I add transactions that have not imported from the bank account?

I can show you an easy way in adding your bank transactions, user10712.

 After you’ve connected your bank or credit card accounts to QuickBooks, your transactions are automatically downloaded. If you need older transactions that were not included from the set of bank downloaded transactions, you can manually add them. Let me show you how:

1. Visit your bank's website and set the date range of the transactions you want to download. 
2. Save it in your computer and in a file format that we support such as .QBO, .CSV, or .QFX.
3. Once done, open your QuickBooks Online account.
4. Go to the Banking or Transactions menu and then Banking.
5. Select the bank and at the upper-right, click the Link account drop down and click File upload or Upload from file. 
6. Open the saved file. 
7. In the QuickBooks account dropdown, select the account you want to upload the transactions into. Then select Next.
8. Follow the onscreen steps to match the columns on the file with the correct fields in QuickBooks. Click Next.
9. Select the transactions you would like to import. Then select Next.
10. Click Yes.
11. Select Let's go.

Now that your transactions are in QuickBooks, it's time to match and categorize them. The transactions go into your accounts after you review them.

However, if you want to record a sing transaction, just click the + New button from the left panel.

Another option, utilize MT Online. It is designed to import into any bank or credit card in QuickBooks Online, so there is no specific setting needed.
