Update: I changed every wth to lower on all of my W-2's and it worked. Even the ones that weren't being flagged. Super cool that the error in the review section didn't match the w-2 with the error on it.
It's genuinely incredibly lazy that we haven't had a fix in 3 years, and that the review section is also broken. This is a pretty embarrassing user experience, especially for a service that costs 3 figures.
