Schedule 1 Free Fillable Forms won’t let me type anything and is not auto-propagating

The IRS free fillable form schedule 1 form is not letting me type anything. I did schedule C but schedule 1 is just not letting me do anything even though I attached schedule C. Does anyone know what the problem might be?

This is the most convoluted system, I think it’s designed to make the experience as painful as possible. I didn’t make enough to justify paying Turbo Tax $500.
