Thanks for getting back to this thread, @REN9.

Changing the amount in the Opening Balance Equity account to negative isn't allowed in the program. This is the reason why you're getting an error message "You must specify a transaction amount that is 0 or greater."

For more details, please check out this article: How the beginning balance is calculated.

Additionally, you can reach out to your accountant for further guidance on tracing the discrepancy in your account. If you don't have one, you can click this link here to find a pro advisor:https://quickbooks.intuit.com/find-an-accountant/
