For 1099-B, TurboTax Mac Download (not online) I am entering the summary information for each sales category. One of the 1099-B entries to be summarized has a value for Box 1f. I click on the box saying, "I need to enter amounts from box 1f... or other adjustments".
The screen updates to ask about the "other adjustments" but no ways to enter box 1f or 1g data, as seen below. This is the entire screen, there is no more to scroll down to. And when you "Continue", I am taken back to the summary screen.
The "Total adjustments to gain or (loss)" seems tied to the adjustment codes, not to boxes 1f or 1g.
