Unallowed Losses from a PTP not showing up on Form 8582

I have an unallowed loss from a Publicly Traded Partnership (PTP) reported to me on a k-1.  The unallowed loss is suppose to be reported on Form 8582 to carry forward for future years.  However, after entering my k-1 data into TurboTax, the loss is not showing up on Form 8582.  How do I get the unallowed loss to show up on Form 8582 so that I can use it to offset future gains?
