I been out of work for 2 years I am trying to get the rest of the child tax credit any help would do

If eligible for child tax credit you can get it even though you have no income. File a return with one dollar of interest if you have no income to report.

Even if you did not receive the advance payments, the Child Tax Credit can be claimed on the 2021 Federal tax return.

This IRS FAQ states:

The American Rescue Plan increased the amount of the Child Tax Credit (CTC), made it available for 17-year-old dependents, made it fully refundable for most families and made it possible for families to receive up to half of it, in advance, in monthly payments during the last half of 2021. Moreover, families can get the credit, even if they have little or no income from a job, business or other source.
