Hi maria94,
Hope you're having a good day!
We're unable to remove a reconciliation report. It will always stay in your records even if you redo your reconciliaton for a particular month.
On the other hand, if you want to see some references for QBO, you can visit the main support page, scroll down a bit, and click More topics.
If you have any other concern about reconciliation, feel free to go back to this thread.
