Have both 1099-B & Sch K-1; stock was inherited. On 1099-B, date & cost basis reflects DOD. K-1 Sch has date/ basis at 9 mos later (when Corp updated name). TT entry?

The stock was inherited in 2016 and sold in 2018. The brokerage house(s)  used the death certificate with date-of-death (DOD) to provide cost basis which was reflected correctly on the 1099-B. However, the physical transfer of the stock ownership via Estate took ~ 9 + months and the Sch K-1 has different acquired dates and cost valuation (based on the acquired date). However, the K-1 does show the stock as "inherited". My sub questions are:

1) How to handle in Turbo Tax entry ???

2) Should I attempt to get the Sch K-1 revised ? (It's correct from the point of view of the company that created the K-1 as to when the stock went into my name and the value at that time).

3) Potential audit triggers?
