TDCJ Sign On Bonus

Hey everyone

I worked for TDCJ in 2018 and accepted a $5000 bonus. I signed a contract that stated I needed to work for a year (I didn’t) and now I have to pay it back. The state used the net or 3500 I received after taxes and said I needed to pay it all back. They took my last paycheck when I quit and I then had a balance of around 1400. My question is, what will happen if I don’t pay back the 1400? It has been two years and all I get from them are invoices saying I need to pay them back. They don’t deduct from my IRS returns and they don’t deduct from my current job (I work for another agency in Texas). Would they ever send me to collections or make a warrant for my arrest?

Sorry for the long post folks. Just really anxious about the situation
