How do I add a new bank account - manually. No connectivity to online banking. Just for reconciliation purposes.

Thanks for joining this thread, @NJO. 

Yes, you can simply create a new bank account and add transactions to the register manually. To manually add a bank account in QuickBooks Online. Here's what you need to do:

1. Select Accounting from the left menu.
2. Choose Chart of Account.
3. Click New, then fill out an Account Type, Detail Type, and Beginning Balance.
4. Lastly, select Save and close.

Then, start uploading your bank transactions in QuickBooks. For detailed steps, please see: Manually upload transactions.

After adding the transactions, you can start categorizing or adding them into your books. When you're done, you have the option to start reconciling your bank statement. I'd also recommend reading this article for a reconciliation guide: Reconcile an account in QuickBooks Online.
