Hello @vipin-mdb-gmail-,

Let me help share how you can connect your account in QuickBooks for online banking.

Normally, you can connect your account without any trouble as long as you're able to find the exact match of your financial institution base on its name and website.

Considering the message of your initial post, the account suggestion is not what you need and you're unable to find the exact match.

With this, let's consider sending a request for the support of your account by following the steps below:

1. Go to Transactions.
2. Select Banking.
3. Click Link account.
4. Scroll down the page until you see the Show more option.
5. Select Still can't find your bank.
6. Enter the name and website of your account.
7. Click Request.

In the same manner, here's an article you can read to learn more about how you can identify your account: Find your bank or credit card account when you connect to online banking.

On top of that, I've also included this reference for a compilation of articles you can use while working with us: Banking for QuickBooks Online.

If you have any other questions, please let me know by leaving any comments below. I'll be here to lend a hand.
