Good morning, @Foresight00.

At this time, there's not a way to view employee's timesheets more than a year old in the Weekly Timesheets in QuickBooks Online. I'm going to submit feedback to our Product Development Team about bringing in a feature that will allow this to happen. You can visit our Blog to see what's new in QuickBooks Online, as well as seeing what's coming in the future.

If you have additional questions or concerns, please don't hesitate and reach back out! Have a safe weekend.
