Hi valjd,
It's nice to see you in Community. Welcome! QuickBooks Desktop has everything you need to accomplish your daily tasks seamlessly. I can see how managing your accounts can be concerning in situations such as this. I'd be happy to help!
Based on the information you've provided, I recommend speaking with an accounting professional for their expertise and best course of action. Although you can add accounts to your chart of accounts and apply an identifier, such as '2023', you need to ensure it will have a positive impact on your books. If you don't have an accountant, we can help you locate a ProAdvisor in your local area.
If you have any other questions, please don't hesitate to reach back out. We're always glad to assist!
