"The IRS unexpectedly merged two separate Payer’s Tax Identification Numbers (TIN) used by Ohio DC. Form 1099-Rs were originally issued with an inactive TIN. Per the IRS, Ohio DC participants should file their taxes using an updated Payer’s TIN. A revised Form 1099-R containing the updated Payer’s TIN has been posted to your online account. If you are not enrolled in eDelivery, a revised Form 1099-R will be mailed."
