K1 question-/ What's Wrong . Turbo says " Enter your liability Share : Nonrecourse " . it is 0.000125 percent, but Turbo says this is an "invalid number "....

The IRS requires that there be whole numbers only. 

I would just enter 1.

Answer incorrect/invalid as i have already entered  0.00##% for other K-1 holdings

Have you tried 0.001%   That is a very large decimal percentage unless the company has a large amount of non recourse debt and/or shareholders.

tried but still "invalid number". yet 0.002406% was accepted by TTx for another K-1

The smallest number TurboTax will accept for non-recourse debt percentage is .01

i apologize  my question was incorrect

Not a problem. Did you get it to work for you?
