I received Schedule K-1 form 1065 from ETF (partnership). Same transaction is reported in Form 1099 B received from my Broker. How to adjust 1099B to avoid double tax?

The K-1 form (final K-1) has Cost Basis different  (lower) from 1099B. It shows a capital gain as I liquidated it within 1 year. I entered both the form details in Turbotax. Now the choice is
1. Delete the entry for the ETF from 1099B transactions and keep K-1 only
2. Adjust the cost basis in 1099B transaction so that there is no capital gain from that transaction and keep K-1 capital gain only

Let me know which is the better of the two and is there any other options as well?
