Hello there, @lee-a-jury.
With QuickBooks Online, you have the ability to organize your account information based on your preference. Let me furnish you with resources on how you can manage your imported Chart of Accounts.
While there's no way to completely delete an account from your Chart of Accounts, you can opt to make this account with zero balance as inactive. This way, it will be hidden from your Chart of Accounts list.

Please note there are accounts created by the program depending on your company setup which you cannot delete nor make it inactive. For additional insights, you may check out this article: Delete special and default accounts in the Chart of Accounts.
