You shouldn't have to enter the recipient information for the 1099-R at all. TurboTax will pick it up automatically from the personal information that you have already entered. But if you do have to enter it for some reason, enter your full Social Security number as the recipient's TIN. Do not enter it with asterisks the way it is on the form that you received. It has to match your actual Social Security number, not the masked number shown on the form.
The recipient's TIN is generally the Social Security number of the person who is receiving the form, more than likely the TIN is your SSN.
The payer's TIN is the number of the company that issued your form, if that number is missing you would have to contact the company.
On the TurboTax Form 1099-R there is not a box to enter the Recipient's TIN. You are asked prior to starting who the form is for if you are filing jointly. Otherwise the program knows your SS number and there is no need to enter it on the Form 1099-R.
