I'm getting the same error as the OP. The response from AkinaLO doesn't seem to make sense, as the question is how to fix that error, not how to deal with having multiple accounts.
TurboTax does not appear to know how to fix the error, either, as it just says "double check everything and then refile"... i.e. not much help.
My specific question: My form 540, line 71 exactly matches what the CA FTB's website lists as my 2020 withholdings, so how and why am I getting that rejection message?
