I never was able to open a ticket. I honestly don't even know how to open an official ticket. I couldn't find that option anywhere. What I was able to do was open a "support" chat on the TurboTax Facebook business account. That's where I chatted with various people, and we tried all sorts of bizarre things to zero success.
I'm completely mystified with who reinstalled Windows 11 and had things work. That makes zero sense to me (I'm an OS developer). I did try my imports on multiple computers and multiple OS's (Windows and MacOS). Never worked. My speculation of line length is just that, speculation. I just entered things in manually again, which completely sucked, but I didn't see this getting resolved. And I'm not going to be the validation department for a product I spent money on.
