amend taxability of Social Security

I inadvertently hit the button on the top of my social security input page which did not tax any of the social security.  I didn't catch the error and e-filed the 2024 return and now must amend.  Going through the step-by- step amendment options it does not offer any adjustments to the social security income.  How do I change the SS payments to the normal taxability in the amended return?
