Hello there, randie4620. I'm here to provide further clarification about your compatibility issue with QuickBooks Desktop (QBDT) for Mac.

You can continue using your QBDT for Mac 2019, but please keep in mind that this version has been discontinued. As a result, you will no longer receive security updates, patches, or access to live technical support for any issues that arise, nor will you have access to other Intuit services that integrate with QuickBooks Desktop. Please refer to this article for more details: QuickBooks Desktop service discontinuation policy.

Currently, the only compatible versions of QBDT for Mac that work with Sequoia are:

• QuickBooks Mac 2024 R5.1
• QuickBooks Mac 2023 R7.2
• QuickBooks Mac 2022 R12.1

Since the option to update for free is unavailable, I recommend following Chrea's suggestion to reach out to Fiat Lux for further guidance.

Additionally, I'm adding this article again about creating a save point for your company file: Back up your QuickBooks Desktop for Mac company file.
