Entered a lot of deposits as journal entries - not deposits - can I somehow transfer them? Or do I need to delete the journal entries and re-enter?

I am new to QB.  My bank only transferred back through June.  So I entered by hand Jan-May... through the check register... but I guess it went in as a journal entry.  But now I need to go back through each deposit and add customer payments....  not allowing me to do that in the journal entry.  I am hoping there is a way to transfer?  I was going to do a bank rec. and see, but my archived statements don't have beginning or ending balances.  Also ran a PNL and some of the transactions are there, some are not.

Do I need to restart?  Delete journal entries?
