Employee & partner GST/HST Rebate

Filling up my return using TurboTax Premier Download and the summary pops up $8.05 as "Employee & partner GST/HST rebate". 

Searching through the whole return and could not find where this $8.05 comes from or how it was calculated. Other than is mysterious figure, everything else appears to be OK. Please help resolving this $8.05 mystery.

Thanks
