We have had the same issue of all of sudden it not exporting from payroll to our Quickbooks Online.  I have sent reports showing the error I have been receiving - Invalid Reference ID:  Accounts element ID 128 not found.  The state its because I have a another payroll which we do not.  We have been exporting and doing the same thing for years.  All of a sudden now it will not work.  I have noticed it is sending my payroll data to a liability account we have set up.  It is obviously some glitch in the system and I still keep waiting for them to fix this issue and address it properly.  They told me I need to upgrade to the advance...This is laughable.  I have to pay more money to get your program to work properly?  Fix the issue....
