This worked for me. I had old offsetting JE from 2019 and I was able to get rid of them.

Go to the year the JE was created

AR

Select new

Select receive payment enter the customer name and leave the amount received blank

for the payment date, enter the date you'd like to use for an invoice closing date for your reports. Under outstanding transactions, put a checkmark next to the invoice to be paid with the credit. under credits, put a checkmark next to the CREDIT. choose save. the zero balances should now be gone from the AR. "Now I need the solution to remove old offsetting JE from AP"  I've tried everything
