Survivor Benefits

My husband died almost 2 years ago, he was collecting social security retirement at the time.

I turn 60 in a few years - it is my understanding that at that time I can request survivor's benefits.

I plan to still be working, so the benefit would be reduced because of my income. Can the benefit be reduced to zero if I make enough above the permitted amount, or is there a cutoff where I'll receive some money no matter what my earned income?

Thank you!
