The state of Illinois expects prepayment of tax if you owe more than $500 the previous year. Turbo tax didn't add vouchers to my final return..How do I get them?

You can go through your state return and keep an eye out for the question that asks if you want to prepare your state estimated vouchers. 

Or as an alternative, here is a link to print blank vouchers for Illinois estimated payments:
