I have a corporation that needs to file federal and state returns for 2011-2017. I have CDs for all but 2014, but when trying to install the 2011 corporate application I received a message saying that it's not configured to work with Win 10. How may I go about completing these returns with Turbo Tax?
Unfortunately some of the older years may not work with newer versions of Windows. Anything prior to 2014 may not even be able to be updated, since once the statute of limitations on filing has closed, TurboTax no longer supports the older versions.
Have you tried installing or updating any of them yet?
