How to terminate small business under my SSN

Turbotax support,

 

I used to do Uber business under my SSN and filed Uber income on my tax return for the past few years.

 

But I stopped doing Uber in 2021 and will not go back into that business any more. How do I terminate this business filing on my tax return or anywhere in Turbotax that I can mark there is no more business income under my SSN for tax return filing ?

 

Thank you very much,
