Get your taxes done using TurboTax

Ok, the software is telling you it downloaded Louisana, but it does not actually download.

 Also, I am assuming you do not see anything like this after you download in the state section:

If this is the case, the first thing I would do is set up a dummy second account and see if you can import the Louisana software there. If you can, then the problem is likely with your return .tax file. If you can not then the problem is likely the software. 

If you are unable to set up Louisana in the second account, I would preserve your .tax file and delete and re-install the TurboTax software and see if that does anything for you.
