Call a function if a checkbox is selected google sheets - if-statement

Question

I am trying to find a solution to the issue I have.
I have checkboxes in column A. What I need is when one of them is checked, to populate a function/formula in a cell next to it (column B).
For example, I checked the checkbox in cell A10 and formula is being populated in cell B10.
The formula/function I have is a long IF function.
Hoping someone will be able to assist.
