Hi there, @KM2023.

With the launch of QuickBooks Desktop 2022 and Enterprise 22.0, some features are no longer available. And one of these is the QuickBooks Pro Timer. As a result, importing timer activities is not an option when upgrading to Enterprise Solutions 2023 Desktop subscription.

As a workaround, you can consider visiting the QuickBooks Desktop Marketplace, which features third-party applications developed by our independent developer partners.
