If I selected pay electronically will my IN taxes get paid electronically or do I need to send in a check with the voucher? Do I need to send in just the voucher?

I put in my bank info to pay my taxes electronically on turbo tax for federal and state... I recieved an email saying that I need to print off and send in my state taxes... will they get paid electronically or do I need to send a check to the Indiana department of revenue with my taxes? Also do I need to send in all my tax info i.e. W2s and tax return info or just the voucher?
