But deleting the check won't mess anything up?  The check was already cashed and it's matched.  That month is already reconciled.  I did these transactions back in Oct. 2024

Also, what is the correct way to do a refund to a customer that doesn't have a credit balance.  They have no balance.  That's what happened with this one I am currently talking about, and I have another refund I have to process to another customer that has no balance.
