Why isn't schedule 3 being generated to recover social security tax withheld?

I'm trying to recover my excess withheld social security tax. This should be doable in 1040 schedule 3 (which exists for 2019: https://www.irs.gov/pub/irs-pdf/f1040s3.pdf

However, it doesn't look like Turbo Tax has any option to generate this form? Any reason why?
