Welcome to the Community, @dneill. I’m here to assist with the tax checklist in QuickBooks Self-Employed (QBSE).
Right now, there’s no specific time for when the option is available or rolled out in your company file. Rest assured that once the application is ready to file taxes, the tax checklist will be obtainable on your end.
For future reference, you can follow these steps to start reviewing once the checklist is available:
Log in to QuickBooks Self-Employed, and select Home.
Tap the Tax checklist link next to your profile⚙ icon.
Select a task on the list. This takes you to the task so you can finish reviewing your data.
