Retirement tax questions

This is not working correctly in latest turbotax online

I made non deductible contribution to IRA. Followed all the instructions here.  When i fill up 1099-R form in turbotax, it still adds tax.  On form 1099R, if i make Box2a - 0 , then it correctly removes the additional tax. 

For some reason, turbotax is still not able to recognize Box2a as non taxable income.
