TurboTax doesn't support online amend 2021 tax return. Instead, I had to download a TurboTax to my laptop (Windows). I followed the instructions and amend the federal return of 2021. The change is in federal return, but the effect only shows in state return. The problem is that even though the app (intuit turbotax amend) shows CA Refund is $339, but the amended return Summary says "We don't detect any differences between your original 2021 return and your amended return. if you're sure you need to amend, explain why below." I explained but when reached to the page of "We're ready to file your taxes", and continue button doesn't work.
