Hi Ecko1,
Thank you for reaching out on this.
You are not required to re-report employees whose finish fortnight has already been reported and still applies. Nor are you required to report a finish fortnight for employees who were eligible for JobKeeper 1.0 payments but are not eligible for JobKeeper 2.0 and so received their last JobKeeper payment in the 13th fortnight. In this instance, simply stop reporting any JobKeeper top-up.
For more information, please visit the following post to the ATO community on the same topic:

Thank you and please let us know if you require any additional assistance.
