You can manually import your transactions as a batch in CSV format.  Once you've created the file and saved it to your computer, you'll be ready to upload it into QuickBooks Online.  Here's how;

1. From the left menu, select Banking or Transactions

2. Use the ▼ dropdown menu beside Link account and choose Upload from file

3. Select Drag and drop or select files and then select the file you've created and saved

4. From the QuickBooks account ▼  dropdown, select the account you want to upload the transactions into.  If you don't see one, select Add New ▼ from the dropdown to create a new bank account.

Then hit Continue.

Here's a helpful guide for your reference.
