I have been waiting for a response to this issue. I have contacted TurboTax support multiple times.
The article that was previously linked from this message is no longer available as of this morning, 5/8/2022.
I can't find a newer or updated version when I search for the "DCN has too many characters" error either.
I did sign up for updates from that original TurboTax posted article. I have received no email updates on the matter.
I am unable to file my state taxes for Louisiana as a result of this error and according to the software, Louisiana requires e-file.
I am very disappointed in TurboTax if they have now put their head in the sand and are ignoring this issue.
