I work a job that has me travel all across the country; I have 20+ state returns to file this year. (Don't get me started). I'm trying to figure out the best software and way to do that - I know a majority of them will need to be mailed in as I can't afford the exorbitant turbotax efiling fees (I'm a musician, not a Wall Street billionaire) but I'm not sure my best course of action.
TT should be able to handle ; however the software is $40 each... and then you’ll have to paper mail most of them
But may still be worth it to you for time and convenience
And even if you did attempt it with TurboTax...you would have to buy and download and install the Desktop/Download version for 2018. (And it only installs on a full Computer Windows 7 or higher, or a full MAC with OS X 10.12 or higher)
Even though TT could handle it, there is only one free state return included. The other 19 will cost ~$20 each [EDIT: I saw in another posting that the additional states are $45/each this year!]. Most states offer a way to download their documents free online (PDFs) and/or have free online filing.
