1099-R Distribution Percentage. Smart Check Error

 

I received a 1099-R for a lump sum distribution from a passed relative's 403b plan.   I was one of 8 beneficiaries.  The 1099 has 12% in box 9a and the Total Distribution box is unchecked   Smart Check reports an error saying that box 9a cannot have a value in it, if the Total Distribution box is unchecked.   How should I fix this?
