You have to be very careful to print out your tax return, and read the filing instructions every year. There are two separate filing/payment instructions, one for the IRS, and another for the state.
Many states will only take mailed checks,, or require you to pay on the state's own website, and not when you e-file with any software company's tax program.

In the years before my own state started allowing e-payments to be set up with the tax e-filing (NC), you could select the state electronic payment option as part of the filing process, but if you rushed thru the filing process too quickly, you'd miss the detailed instructions saying you actually had to use the state's website to pay separately.....Those instructions for paying the state are also in the PDF printout (AFTER filing).
