How can i remove/delete a bank account from Current Assets. account added in error

I'm here to provide information about removing your bank account in QuickBooks Online (QBO), drtulifau1. 

In QuickBooks Online, users can delete accounts that are no longer in use. Once deleted, the account will be marked as inactive in the Chart of Accounts. The deletion of an account will not erase the transactions contained there, so reports won't change.

Here's how:

1. Go to Settings and select Chart of Accounts.
2. Find the account you want to remove.
3. Select the Action dropdown and choose Make inactive.

In case you'll want to visit your inactive accounts in your chart of accounts:

1. Select Settings, then choose the Chart of Accounts.
2. Next to the printer icon, pick the Settings ⚙ icon.
3. Select the Include inactive checkbox.

I've added this article so you can get more information and find out how to make an account active again: Make an account inactive on your chart of accounts in QuickBooks Online.
