How to report sales with no 1099-B form from overseas brokerage

I am using a desktop version of Turbotax Home & Business 2024

 

I have been successfully using this software for many years, but I am running into a snag (I didn't have any problems last time, reporting income and/or losses from sales of stock on a foreign stock exchange) reporting major losses from 2 sales of stock in 2024.   The brokerage in question does not issue any 1099-B.

 

How do I enter my losses?

 

I would value a recommendation on how to do this very much!
