Get your taxes done using TurboTax

I'm also using the Downloaded version (premier).  It keeps telling me I made a Excess contribution b/c I did a back door conversion and wants to charge me a penalty.   But it isn't t taxing the distribution.   The original IRA was non deductible & Turbo tax has the correct cost basis,  It appears I'm have the same issue as a poster above.  Someone please help.  I know we can do this w/ no issues.  Why doesn't the software recognize this?

I talked to the "help desk" at Turbo tax & they told me I needed to upgrade to Premier, that didn't do any good.
