Can An Death Benefits For My Children Be Used As Income For Child Support

So for context I have 3 children(2 from a previous partner and one with my current partner). My first two children receive death benefits due to their mom having passed away a few years ago. My current relationship has become extremely toxic and idk if I can continue on with it. Nothing is set in stone but I just want to know if we were to separate and I were to pay child support would the death benefits I receive on behalf of my other 2 children be used in determining how much child support I would owe? This would be in TN as well. Thanks ahead of time.
