How to enter IAU Gold Trust ETN transaction reported on 1099-B as collectible

I've held the IAU Gold Trust ETN for many years and have no trouble entering into Turbotax Premier the small monthly sales that are reported on my 1099-B to cover the fund expenses.  The gain on these transactions should be reported as a collectible sale.  In the past, I had no trouble entering the investment type as collectible for these transactions when I enter them with the rest of my 1099-B transactions, but the option to select "collectible" as an investment type appears to be gone in 2024 Turbotax Premier.  How do I enter these collectible transactions reported on my 1099-B?
