Error 190 when attempting to amend a filed 2024 CA S Return

[blipisko1]

I'm attempting to clear Error 190 and amend a previously filed S Corp  return.  I understand amending the return requires the download of a state form.  The list of options does not include an S Corp, only partnerships or LLCs.    Any suggestions as to how to proceed?

If you previously e-filed your California S-Corp return using TurboTax Business, the state module should have already been installed. 

Two options to try:

1. State install/e-file update loop: State not installed after installation or TurboTax needs to update....
2. Error 190 when opening file in TurboTax Desktop.
