If the state allows you will have to create a 2nd return within ProSeries.  First, after completing joint Federal go to File Menu and elect to split into MFS.  This will keep the original data file and create two new one (TP) and (SP).  You can either have one file for joint and two other files for state or on the joint file you can get rid of the spouse's data in the state.  Either way verify for accuracy as some things may need to be corrected (who claims what child, split of charity, etc., etc.).
