UPDATE 3/3 @ 12:15AM: The problem seems to be resolved online and desktop users of TT now!
Worst case, you can always also just print your PA returns out (TT has all the forms filled out) and file by mail if you cannot wait (however you should ensure your 100+ transactions are all accurately reflected on those forms prior to mailing.)
Thanks to everyone who has been providing feedback and helping us figure this out, while this was annoying and frustrating, it does seem like TT was working on the fix and just got it deployed later than expected. Best of luck everyone!

UPDATE 2/28 @ 12:45 PM (EDT): Submissions are still not working, same error. The consensus seems to be that TT will now have the needed fix in place between March 1st - March 3rd. Please keep replying to this thread with any new info you get, I will update my answer here to hopefully help others trying to figure this out.

Just got off a long call with TT, turns out that PA is the culprit here.
The PA E-file system doesn't allow e-filing of the Schedule D form until 2/28 or after - this is why e-file fails but you can still print and mail the form in.
Easy solution: wait until 2/28 and attempt filing again then. Hopefully that actually works...
