I filed our businesss return through TurboTax online a couple weeks ago, but I need to add another state. There's no "add a state button". Is there a workaround?

The personal version of TurboTax has an "add a state" button, but I'm not seeing one when I've selected my business return. I just see a page that says "Congrats! Your business taxes are done.", with some options to review/download the return, but no ability to add a return or to amend the return. Is this a bug or a known limitation of the business product?

Looks like the answer is "you can't". I talked to a support person over the phone, and they said:

• In TurboTax, you can only add states for business returns by amending your original return, which means resubmitting the previously-filed returns.
• You can only amend business returns in the desktop app. It's not available in TurboTax online.
