Business & farm

Because TT didn't' come up with an update yet for the $10,200 UC tax exception I'd like to edit line 8 of Schedule 1 myself. 

When I try to enter something on line 8, and a numeric value, it seems as if the field is locked. 

I click on the line and then it takes me to the 1040 form. 

According to the IRS the UC tax exception of $10,200 can be put on line 8 of Schedule 1.

But, turbo tax wont let me do that!

Who can I enter a value in this field?
