On the 1099-R page there is a button for a substitute 1099-R, but it does require the payers TIN. Contact the payer and ask for their TIN.
If you cannot get it then you will not be able to e-file, leave it blank and print the return and write "Unknown" in place of it and mail the return to the IRS.
