The previous accountant has passed away and I am trying to complete the tax return.  There is a worksheet stating NOL has been carried forward from 2010 and I have a total amount.  I also have the last 3 years of tax returns which is over half of the NOL.  Any ideas how to account for the other NOL years? 

There is someone who can access the ProSeries tax software but they are not sure where to find the information in the program.
