I am having a problem with this. I got a lump-sum for 2018 in 2019. I’ve entered that. At the end, Turbotax says there are errors to correct. It says that our earlier yr taxable SS ben-TP should not be greater than zero. However, we filed jointly and our 2018 return on line 5a shows what she received. How can that not be greater than zero? When I look at the form, it appears to be filled out correctly, but this keeps giving me an error in the Smart Check. How to get past this?
