State Download is not working

I have my Federal Taxes done and have been trying to download my state since last night. Nothing I do works and at this point I am very frustrated. I have Turbo Tax online version. My cell phone number is [phone number removed].

I had the same problem. Endless loop. CA state wouldn't show up. Tried all the advice given online as well as the help of a tech support person over the phone. Nothing worked. I finally figured it out, though.

Here's my relevant backstory: In my case, (prior to encountering the endless loop problem) I had originally purchased the Deluxe version. Then I realized I needed the Home and Business version. So I uninstalled the Deluxe version using the TTax uninstaller. Then installed the Home and Business addition.  OK  so far. Then I put in all my info, OK so far. Then tried to download the state. No luck. Tried over and over, uninstalling and reinstalling TT, etc. 

Here's how I finally solved it. I looked in my C: > Program Files (x86) > TurboTax folder. There was my Deluxe version that I had already uninstalled, still there in addition to my Home and Business version. Aha! Defective TT uninstaller! So I looked in that Deluxe folder. The only thing there was the Forms folder. Looked in there, saw 2 folders: 1040_## and cai_##. CA stands for California. So, I figured that CAI folder must be the CA forms I need - even though I definitely did not download the CA state forms while using the Deluxe version. So I figured the defective uninstaller did not remove all the TT Deluxe info from the registry, so the installer for the state forms saw TT Deluxe info in the registry so it put the CA forms there by mistake (even though I was using the Home and Business edition to download the state forms). So I copied that cai_## folder to the Home and Business > Forms folder, restarted TT H&B and it worked! There was TTax telling me that I owe money to CA. Sigh. At least not as much as I was expecting. Yay?

2/19/2022: I just spent 9 hours on TT Home & Business 2021. But solved problems not recognizing two states (NY free, CA paid), and not allowing electronic submission of returns to IRS, NY, or CA. Solution was to entirely delete TT Home & Business 2021 from my Windows 10 PC; then double-click on the original paid download (after paying for it Dec. 2021, I had saved it in my DOWNLOAD Folder as "TurboTax_Home_Business_2021_PC_Download" exe), BUT MAKE SURE to save it IN THE ORIGINAL Download Folder and location. This is essential. Don't let it save in the newer Individual 2021 Folder (if you've unsuccessfully been trying other options). That solved the "The Intuit Electronic Filing System is having difficulty ... (and) FAILED VALIDATION ... " errors, which just kept me going in a circle for hours.

I have the same issue in 2022 as WYTSTANG in 2020.  Purchased Premier 2021 with 1 free state and am caught in the endless cycle of downloading the free state but when I hit start, a window pops up to start the purchase confirmation and download again.  

Go to menu at the top – online – updater preferences – turn off auto update.  The program was obviously updating instead of downloading.

Your answers don't work. When I call your number, the robot can't understand my issue (the state return won't install) and won't connect me with a human.
