MLP Sale (MMP acquired by ONEOK) fun

Turbotax has been very unhelpful with what one would think is a relatively common transaction, which this year must have affected thousands of investors due to the sale of MMP forced by the acquisition (I tried their tax experts and even full service, with no success)

My broker reported the sale of multiple lots of MMP with "cost basis Not Reported to the IRS", and they were imported in section Form 1099-B "Stocks, Cryptocurrency, Bonds, Other"; however they were marked as "need review", and the wizard required to manually select the investment type (ESPP, RSU, stocks, ETF etc) but there was no category matching "Partnership", so I manually deleted these entries, and proceeded through the K-1 section. 

At the final review, in the generated form 8949 TurboTax somehow has reported the proceeds as a single transaction, and checked box (F) - transactions not reported to you on form 1099-B; however the correct box should be (E) - transactions reported on Form 1099-B showing basis wasn't reported to the IRS.

This seems incorrect, and I suspect it could be due to me deleting the sale entries from the "Investment Income 1099-B" section "Stocks, Cryptocurrency, Bonds, Other" section, but I'm clueless at how I could have reported these in that section since there was nothing matching the investment type.

Anyone had the same problem?
