Good morning, @wheelsdj! Thanks for coming to the Community with your question. I'm happy to help you get those fields back. I'm going to direct you to a setting in QuickBooks Online. 

1. First, sign in to QuickBooks Online as the Admin of the account.
2.  Click on the Gear icon.
3. Select Account & Settings.
4. Click Advanced then select Time tracking.
5. Click the pencil icon to edit. Here, make sure:

• Add Service field to timesheets is enabled
• Make Single-Time Activity Billable to Customer is enabled

Then click Save.

After that, go into your QuickBooks Time account and run an import from the QuickBooks menu in the upper right-hand corner. 

Please let me know if this fixes the issue. I look forward to hearing from you!
