We are both on SSA, and will never owe taxes in the future. We have a carryforward tax credit of about $11,000. Is there any way we can cash that in. OR is it lost?

No. A carryforward tax credit is only usable when you have a tax liability.  So unless you have additional income that creates a liability, you would not be able to use the credit.  You cannot "cash it in".  It is use it or lose it, so unless something changes, it is lost.
