I know HOW to delete it.  But when I do, it throws my bank reconciliation out of balance again.  The entry came out of nowhere AFTER I reconciled the bank successfully for 15 months, the problem came up when I synced the bank to QBO.  It adjusts this large number to the P/(L).  

The issue is with syncing a bank account after manual transactions have been entered.  I set up a bank account when I set up the company.  Then I entered 02/01/2022 transactions manually through 04/30/2023.  I successfully reconciled those months with no problem.  Then, I synced the bank, specifying a start date of 05/01/2023.  QBO created a NEW bank account, downloaded all prior transactions.  After an hour on the phone with support, I was told there was no way to merge those two accounts.  So I had to manually move all the transactions I had entered into the QBO-created bank account.  When I tried to reconcile the account, a large adjustment was required.  I have no idea where the amount came from.
