Links to financial institution for data import

[jnfrench]

I have Home and Business Desktop. After importing the data, I searched for the list of linked accounts to disable access, but I couldn't find it in any menu in the product or the Intuit on-line account. This is a major security concern because even if I change my password at the financial institution, the 3rd-party link remains, and I cannot separate it from my TT or Intuit account. Please advise.
