Well---the two of you have made some mistakes starting with "we file taxes together." If you are not legally married you cannot file a joint return. Did you do that? Or did your BF claim you as a dependent on his tax return---that makes a big difference.
If your income is Social Security, no, you cannot get child tax credit or any other child-related credits because those credits are based on income earned from working.
If your BF is the father of the two children then he can claim them as his dependents--it is unfortunate that his delinquent child support causes his refunds to be seized, but that is how it works. The money that was seized is not your children's' money although you want to think of it that way.
A person who owes back child support will not receive a stimulus check.
We need more information on how you and your BF filed.
