After updating TurboTax Premier 2023 on my desktop, I encountered an error message stating “no valid sequence could be found.” Despite trying various recommended solutions, none resolved the issue. I attempted to uninstall the software, but the same error prevented this. Consequently, I manually deleted the program files and all TurboTax 2023 references in the Windows registry to forcefully uninstall the software. Upon restarting my computer and reinstalling the software, a new issue emerged. Although I had previously downloaded a state form, an error message indicated it wasn’t available, and I was stuck in a loop attempting to download the state form. I found a solution to this problem in a TurboTax Community post titled “State install/e-file update loop: State not installed after installation or TurboTax needs to update prior to e-file”. After implementing this solution, both issues were resolved, and my TurboTax application is now fully operational."
