MikeW53, I have gone through the same issues that you have experienced. And, yes, I believe that part of the problem is that the computer I used to file my taxes had about 20 years history of TT information on it. The way I finally got around this issue is to use an entirely different computer that had never used TurboTax on it. I downloaded TT on it, and also copied only the 2022 TT file on a thumb drive and loaded it on the other computer. (This was to save the import of the carryover information from 2022 to 2023.) It worked perfectly.
I believe TT 2023 (deluxe or Premier....as I ended up buying both trying to get something to work), that will block communications with both the updater and the filing software if you have older copies of TT on your computer. No proof, but obviously, the proof is the fact that a new computer without any prior TT information on it did.....finally work.
Hope this helps.
