MLP K-1 Long Term Sale - How Do I Enter K-1 and 1099-B???

I purchases shares in a MLP back in 2011, not realizing what I was getting into at tax time. The purchase and distributions, which were reinvested. Distributions stopped several years ago. I sold ALL shares on 11/22/2021 and residual shares sold on 11/24/2021 for a capital loss. 

I downloaded the Turbo Tax package from the MLP and imported it in TurboTax Premier 2021. I have been able to file the taxes in Turbo Tax each year, but selling/liquidating all the shares is much more complicated. Even though I took a large loss (large for me), TurboTax shows I owe a substantial amount in Federal taxes.

This is the first and only time I sold shares, so I have never dealt with the MLP Sale Schedule and corresponding 1099-B resulting from the sale.

Below is an example of my Sale Schedule and 1099-B information.

Below is the information that I have entered:

Enter Sale Information: I am not sure what to enter into these fields.

Describe the Partnership: All of my investment in this activity is at risk.

Any help that can be provided would be greatly appreciated! Thank you!
