State tax filing

Update, for all those that use Turbotax.  They guarantee nothing.  Their technical support is laughable.  Today's call which lasted just under an hour resulted in the tech telling me that Turbotax no longer supports that, and that the previous tech should not have told me that it could.  Turbotax does not support filing previous years returns, even though the due date of this return fell in the current year.  I can not file a return using a product I specifically paid for to file to do so, within the timeframe for filing that return.  The tech today refused to elevate the ticket even though I asked multiple times.  I used this for filing this return for the prior 7 years without problem.  They answer I was given to that.  "if you read the fine print on the website under filing previous year returns, it states that abilities and pricing can change at any time".  That is the kind of customer service you get, zero retention strategy.  When I asked about the level two tech that told me it was a Turbotax issue, todays tech assured me that it would be escalated and they would be punished.  What complete BS.
