I have QB 2019 for Mac, R7 Desktop
Your instructions for getting tech support have not been helpful, as the menus do not offer what you directed. I finally found the Chat Help and explained my problem. She transferred me to an accountant that I would be required to pay for services. BUT this is not an accounting problem. It is a QB TECH problem. Please read my post below and either call me or give me a number to call to fix this.
In doing my 2019 taxes, I discovered that a final journal entry I made in 2018, was posted by QB in it's entirety to Accounts Receivables, completely ignoring the accounts that I entered in the entry. We are on a cash basis and now our AR is reflecting this incorrect balance.
