income execution

Hello I was sent an Income Execution Letter in March, this was the first I had heard of this. I called NY Tax and Finance and they stated they have been sending notifications to my old address for 2 years! They did have in their system that all letters were returned to their dept. I spent 2 hours on the phone reviewing the Levy and they stated it was from 2014.

Today I received and Release of Income Execution notice. What does this letter mean?
