Hi there, @jbuchal.

With the launch of QuickBooks Desktop 2022 and Enterprise 22.0, some features are no longer available. As a result, importing timer activities are no longer available in QuickBooks Desktop, and it includes QuickBooks Pro Timer. 

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