I have dowloaded but I get error 190 -- download state. I have 2 states that I downloaded with both 2016 and 2017 turbotax. How do I get the states that I purchased?
See this TurboTax support FAQ for an error 190 - https://ttlc.intuit.com/questions/2586090-error-190-when-opening-file-in-turbotax-desktop
The website for the states may indicated that you need to purchase the state but if you continue it should allow you to download your states without charge. If the website asks for a credit card number to pay for the state programs then you will need to contact TurboTax support for assistance in getting your state downloads.
