on the K-1 does is tax basis checked in part L.
if so
report a sales price of $0 since you say you got nothing for basis $0 could be correct. can't be sure because many tax preparers will make entries to zero out everyone's capital account on final return
there is a link to disposition worksheet look for it
if tax basis is checked in part L
you can do your own basis calc
take beginning capital
add any capital contributions
for current year increase/decrease - that's all items affecting taxable income and credits reported in Part III these increase or decrease your tax basis.
certain items are ignored - boxes 6b -included in box 6a, 14, 16 - except amounts for foreign tax and other credits, 17 and some items in box 20 - there are too many possibilities some may affect basis some may not
add income items subtract expenses losses and credits.
some others might point out that technically your beginning basis is the beginning capital account + your share of liabilities reflect in box K., true. but the you must reduce basis for the decrease in liabilities - since ending liabilities should be $0 the decrease would equal the beginning liabilities - so in effect there's a wash.
if your computation results in a negative amount basis , if everything is correct that represents taxable income to you. if it's positive then you have a capital loss.
this should not happen if say for example you at the start of the partnership invested 10% of the capital and through out its life always got allocation of 10% of various items including distributions but if you cane in latter a different result is possible. .
