Get your taxes done using TurboTax

Exit the TurboTax program.
Reboot (restart) your computer.
Launch TurboTax again, and open your 2016 return.
Does your second state program show up now?

If not, then in the top menubar click the ONLINE menu and choose "Download State" again, but don't pay again.  If it tries to make you pay for the same state again, don't.  But report back here.
