we can't tell you. schedule L may or may not reflect your tax basis. can you call the preparer to find out and also why the negative capital contributed. it's unusual to have negative capital contributed. that could be just a plug to zero out your capital. especially if you did not receive a cash distribution of the $8370 that would get reported in box 19 and withdrawals and distributions on schedule L. are there amounts on schedule L?
if you can't get answers you'll have to use your own judgment.
if you didn't get the $8370, that may represent a writeoff of non-deductible items by the partnership which may entitle you to a capital loss in that amount.
