Deductions & credits

I have the exact same problem.  I use the turbotax premier Desktop version and I tried all the combinations you said and it is giving the error. 

 

But to override it, you can instead of clicking Run Smart Check, just click on Done and continue through next step and it allows you to e-file the tax.  I have not e-filed yet, because I didn't want it to be rejected for TurbaTax bug.  I raised a ticket as well with TurboTax and waiting for the fix.  Hope they do it so, so we all get our money back.
