I fully understand what you are going through!  All of my taxes are not computing correctly.  I may have 1 check in the whole run that is correct. I have talked with intuit several times and have gotten several solutions recommendations but to no avail.  I am at my whit's end!!! I have reviewed all of my empolyees set up, W4, and payroll information and I don't find anything wrong.  If I run the check in Online and duplicate it in Desktop there are two different amounts deducted.  Something is not right1
