When you connect a bank account to the bank feed for the first time and there is history in the account, QBO will automatically generate a transaction posting a journal entry between the bank account and Opening Balance Equity for the amount in the bank account on the date prior to the first downloaded bank transaction. 

If you have been using QBO for the bookkeeping and the banks have previously been reconciled, you can simply delete this journal entry and all should be good.  

If you haven't previously reconciled the bank, or if this is a new account, you likely have some additional work to do before you can clear this entry.
