I tried using a substitute 1099-R Form 4852 but that doesn't work too well since Turbotax still wants certain info
you can try the 4852, which still requires you to complete at some sections of the 1099-R then you link it to Form 4852
however, if it were me, I would report as misc income on schedule 1
under the main income tax miscellaneous income - start or update > other reportable income
