Hello there, @BeerOutside!
I'll be glad to help you correct your journal entry and get you to fix your bank accounts.
You don't have to delete the AJE #### Deprec extension. Instead, adjust the JE number if there is a need to correct it.
Then create a JE with a correct number. QuickBooks will then follow the order of numbers once saved.
We'll always be here in the Community if you need a hand.
