Why does turbotax automaitcally fill in a $53 business tax (slef-employment tax) for me?

I am using turbotax home business version. I have a single-member LLC and I report the business income and expense on Schedule C. 

After filing these, TT automatically filled a $53 business Taxes (self-employment tax) for me.  You can see it didn't do this in 2024 preparation.  I didn't enter anything related $53 business taxes.

How could that happen?

And how can I remove it?
