I received a final k-1 how do I post that in my return?

Did you sell your interest or did the entity dissolve? TurboTax will ask you to "Describe This Partnership." Check the box for "This partnership ended in 20XX." This answer refers to your participation in the partnership and not the partnership itself.

On the next pages, indicate how you disposed of your interest (why is this the final K-1?) and details for a sale and/or disposal of your interest. If you didn't sell your interest, then you may have a capital loss on the disposal of your investment.

What I need to know is that on a K-1 received I posted a number, -1168, in box 17E, and I get a response that it's not within the upper or lower limits.  How do I fix that?

What type of K-1 are you entering? Is Box 17 Code E for AMT Deductions or Recapture of a Credit? Both of these options should allow a negative number for Code E. Where do you see the error message?
