It seems to be that roughly the approach karlos and others outline here works fine. I was able to enter code Z on the 1099-B. It showed up on my Form 8949 as code MZ. Maybe I will white out the M. More importantly, the numbers looked correct on how this flowed through to the rest of the return. If anyone knows of any real issues with this approach (other than more complaints that Turbotax doesnt support this more gracefully), I'd like to know.
Yes you need to download and fill out your own Form 8997, super simple, and include it in your filing printout. Yes, you need to file paper. Not a big deal for me as I need to apply my refund to next year's taxes.
This is the approach I am taking for 2019 and will continue with it in future years until hopefully Intuit adds more complete support. I am sure they are trading off how widespread QOZ investment really is among their user base. As someone in the software business, I understand they arent going to do a feature for a very small number of users.
