My client has to file 32 state tax returns.  Last year, ProSeries couldn't handle this.  The software blew up and I had to print and mail paper tax returns.  How can I avoid the same problem this year?  Once Federal is final, can I save a duplicate copy of the file and prepare half of the state returns in the second file?  I would have to manually enter the credit for nonresident state taxes on the resident state tax return.  But, would ProSeries allow the second file with the same SSN, name, address?  If no, do you have any other suggestions for avoiding last year's nightmare?
