Although Turbo Tax recommended I clear my cache and cookies that did not resolve the issue. After reviewing my state returns multiple times I discovered I duplicated an entry within one state return - per the error code I emphasized with Turbo Tax (see error code below) . VA taxes you on income tax from other state(s) income but you can go in and claim each state separately within VA's state filing to eliminate being taxed twice. I apparently had duplicated a state twice and I believe that was causing the error. I believe this because I was able to individually submit all my other returns but could not do so with VA. Needless to say I've spent far too much time on something that the Turbo Tax audit system should have caught and if not Turbo Tax Customer Assistance. Disappointed in Turbo Tax given this is the first time in 13 years I've really needed their assistance and they couldn't seem to assist. The default response was you may have to file by mail.
