After you file

Yes - the corrected dividend did flow through to my state return.  I thought it would show up as a refund after TurboTax reset the state and federal amount owed/refund balance to zero when I selected Amend Return.  For some reason the state balance/refund due stayed at zero (and is why I initially didn't think the corrected dividend flowed through to the state return) because I had previously said to apply any refund to my estimated tax.  So that is what happened.  I thought it would give me a refund but it automatically applied it to next years estimated tax.  On the federal return, the balance/refund amount did indicate a refund.  This is probably because I had a balance due on my original federal return and could not apply anything to next year's estimated tax.  So everything in turbotax worked fine.
