I am in Ohio and having the same issue. My box 16 is empty on my 1099-R. TT wouldn’t let me continue without putting a number in the box. I worked around it to proceed and left the box blank. But, TT won’t allow me to efile without something in that box. TT needs to fix this. I’m not going to put in some other number when the box on my 1099-R is blank.
