One of my retirement payers had an obsolete address, and filed my 1099R to the wrong state.  I asked them to correct it, and they simply resent the form with my updated mailing address, didn't check the "Corrected" box, and left the obsolete state payer ID in Box 13.  They have in the past been difficult to deal with, this respsonse is typical.  I'm trying to get them to correct it, but is there any way I myself can correct the error, and inform the two states of the actual situation?  I'm guessing that the losing state is expecting a tax return and a check; the state where I now reside doesn't tax my retirement income.
