K1 for a partnership that closed in 2018 notes sch L syndication costs may be deductible as a capital loss. How do I do that?

I invested in a REIT in 2008 which ended in 2018 (and didn't make much $$).  The K1 Part II section L "Ending capital account" ends up at 0, but there is a note that says "Included in your schedule L is your share of syndication costs which may be deductible as a capital loss" with the amount at nearly $3K.  How do I take advantage of this using TT and how do I know if the amount is indeed deductible?

Also, what is the proper way to indicate to TT H&B or on the IRS forms that the partnership was closed out?  Which type of disposition is correct?
