I just ran my first payroll with QBO / QBO Time and have the same exact issue. NONE of the hours are showing up even after I spent all that time mapping everything accordingly. I've spent HOURS on the phone today trying to get this fixed and ultimately got bounced back and forth between QB TIME vs QBO. My payroll expert couldn't answer this question yesterday before handing me off to QB TIme. I just wasted 2 weeks of my own time integrating what I thought was already part of my books and now the main point of this functionality is simply not working and no one at QBO seems to be able to help me. 

I switched from ADP because of the horrible service I was receiving and frustration with their lack of transparency in answering questions when they were making major errors and now I'm looking into alternatives again. 

I hope you find a resolve, I am done wasting a single dime or any more of my time with QB payroll. It is not meant for larger businesses within the "small business" category. I have 76 employees, none of which are being accounted for on a single P&L and I've mapped everything perfectly. Such a disappointment
