Just wanted to post another update. I decided to start over on the desktop. I found a MacBook I could use for it. I first downloaded the online version data to upload it. It still contained the error. So I COMPLETELY redid my return from a completely fresh return file on the desktop version. Same result as the online. The only difference is that you can manually select to itemize "if the itemized is lower." However, when I force itemized, my tax due drops and refund goes up, so it's not "lower." The bug is that TurboTax inaccurately compares the standard vs itemized deduction to determine which is better for you.
So the bug affects both online and desktop. No fix was rolled out. I know this affected at least one other person who had an even higher itemized deduction balance than me. Very interesting approach TurboTax has had to this issue. Doesn't give me a lot of confidence going forward.
