TurboTax is not allowing me to file my Missouri state return due to forms not being available, but a simple Google search and here it is https://dor.mo.gov/forms/MO-NRI_2019.pdf. I don't understand the delay
Software has to wait for MO approval of all calcs...
Scheduled to be ready AFTER 30 Jan..
IF you had followed the link I posted just above, you'd see that it is "supposedly" available right now.
Online software users should have access now.
Desktop software users may have to run a software update.
IT would only do so if you have gone thru the entire MO nonresident interview, and populated the exact nonresident values needed. (If you are using the Desktop software, make sure you do a full software update too)
IF you've done that already, call TTX Customer Support and see if they can guide you.
