Hi there, jpark720.

At this time, there's no mentioned ETA for when macOS Sonoma (version 14) will be compatible with QuickBooks Desktop for Mac 2021. The program doesn't fully support yet which might cause the issue you're encountering in the system.

Furthermore, we recommend running the QBDT for Mac program on a supported operating system. Here's an article for your reference: System requirements for QuickBooks Desktop for Mac 2021.

Additionally, you can visit and read this article for more details about storing a backup copy of your business: Back up your QuickBooks Desktop for Mac company file. It also gives you step-by-step instructions on how to set up automatic backups of your company files.
