2023 tax files missing

Using TT 2023 Deluxe desktop I completed and e-filed.  IRS has received but not processed. I called and supposedly a letter was sent 6 weeks ago that I never got.  So I'm preparing for an IRS appointment and needed to reprint returns and docs from 2022/2021/2020.  I reloaded TT 2022, 2021, 2020 Deluxe desktop and now all the 2023 files are gone!  I've seen a couple of issues of this problem.   It has nothing to do with importing a previous year. I completed, printed, and filed 2023 but now after installing previous years TT, the entire 2023 file is gone.
