Is lost income (due to taking time off work) tax-deductible?

This question is for my 2019 income tax return.

 

In 2019, I took some days off work for my elderly father's medical care. He is my dependent in my 2019 tax return, by the way. Since I was paid by the hour, is my lost income tax-deductible?

I would appreciate your answer(s)!
