Champ Hal_Al has an excellent explanation of what to do in his answer to another question posted in Community [Solved: What is a nominee adjustment? - TurboTax]
Q. Can 1099-R income be adjusted to reflect an IRA plan administrator mistake and sending an RMD to the wrong heir / beneficiary of an inherited IRA?
A. No. The administrator should issue corrected 1099-Rs. But more accurately, probably not. It depends on the details of what happened. A nominee adjustment for a 1099-DIV or 1099-Int is shown on Schedule B. There is no place on the IRS forms foe adjusting a 1099-R.
If you receive this as the result of an inheritance, and decided to share with others; you are actually making them a gift, which is not taxable to them, nor deductible (adjustable) by you.

Generally, if you receive a Form 1099 for amounts that actually belong to another person, you are considered a nominee recipient. You must file a Form 1099 with the IRS (the same type of Form 1099 you received) for each of the other owners showing the amounts allocable to each. You also must furnish a Form 1099 to each of the other owners. File the new Form 1099 with Form 1096 with the Internal Revenue Service Center for your area. On each new Form 1099, list yourself as the "payer" and the other owner as the "recipient." On Form 1096, list yourself as the "Filer." A spouse is not required to file a nominee return to show amounts owned by the other spouse. The nominee, not the original payer, is responsible for filing the subsequent Forms 1099 to show the amount allocable to each owner.

I think you misunderstood SamS1. YOU prepare the 1099-R, along with the 1096 transmittal form and send it to the IRS. At the same time, YOU send the 1099-R to the recipient. You can download and print the forms from the IRS website:
