How long for Child Support to be taken off? TEXAS

I married my children father and moved in and want child support off I put a request in since we took off medicaid as well since he put us for insurance through his job this year. Still no word to end it. We need the extra money for Bill's. Any experience ending child support?

They NEVER give the full amount they take from him.

300-400 goes to medical apparently but since medicaid removed I'd wonder what they do.

Honestly so much money goes to their pocket which I get government fees but idk I'd love a receipt what they do lol
