my 1099-B did not provide date acquired, cost basis or unadjusted gain/loss information. I calculated my cost bases and provided the acquisition date, where do I allow for the cumulative adjustments to basis that is shown on my K-1. This basis adjustment is a loss which should reduce my gain on this complete sale of the partnership. Do I use my basis calculation on the 1099 and then put the cumulative adjustment to basis 'add or fix info about sale' in the correction interview?
