Been suffering from this as well. We filed on 5-3 in 2020 (for our 2019 taxes), so we weren't "too late to be in the IRS database". Acquired a 2019 Transcript from the IRS: same AGI # as the one we had saved and used on our submittal. Tried it again anyhow: rejected. Tried 0. Rejected for me but not my spouse (it said 0 was already rejected). So put in the original # for spouse only (Turbo didn't ask for mine again). Rejected with "0 has already been rejected for spouse" message. Getting started on a paper form. Hope we still know how to do that....
