I have a similar issue I hope you can help with. I have several old credit card accounts that we did JE's to bring to zero at year end and the cards were closed. So the accounts had zero balances and cards closed - perfect.

Two months later QBO made an automatic entry on these accounts giving them all small negative balances with an entry to the 3000 Equity account, with the memo being "Created by QB Online to adjust balance for deletion." The next year end we again zeroed out the balances and again several months later, QBO made an automatic entry to the 3000 account and gave all the old credit cards small negative balances. 

Can you tell me why this is happening and how I can close these accounts once and for all and not have QBO make these entries?
