Retirement tax questions

This is what I did:

 

On, the social security benefits, I entered the total amount from box 5 of SSA-1099-SM, which includes lump sums for 2017, 2018 and 2019.

 

I hit continue and entered the lump sumps received for those years; 2017, 2018 and 2019. But that doesn’t change the Federal Tax Due.

 

Even if I omit those lump sums, the tax due stays the same and so does the gross income. So what's the point of entering those lump sums. Am I doing something wrong?

 

By the way, what about amount paid to attorney?
