banking

Welcome to the Community, @suhaas.

Currently, the ability to download bank statements in QuickBooks Online (QBO) is unavailable. You can go to your bank's website and get it manually as a workaround.

Once done, I highly suggest comparing the list of transactions on your bank statement with what's in QBO by simply reconciling them. Here's how:

1. Go to the Accounting menu at the left pane to get to the Reconcile page.
2. Click Get Started, then Let's do it. 
3. Select the bank account in the Account drop-down.
4. Check the Last statement ending date and review the Beginning balance.
5. Enter the Ending balance and Ending date, then hit Start reconciling.

After that, you can now begin comparing the transactions. For further guidance, refer to this article: Reconcile an account in QuickBooks Online.

You can also manually download your bank transaction in the system. To learn more about the process, check out this article: Manually download online bank transactions in QuickBooks Online.
