I converted to QB online in the middle of march 2024 - uploaded the data from Jan & Feb & half of March. At March month end - I had not done enough payroll preparation to pay employees online. So I was advised and did the payroll on the desktop. Now I want to add the March desktop payroll to online. I have original paystubs. 

QB online seem to be reluctant to "upload the March desktop payroll" and the best way seems to be General Journal entries. question - is one at a time the best approach?  (making sure that each employee gets credit for their taxes paid)
