Get your taxes done using TurboTax

I had the same issue yesterday running into the loop. I spent 2 hours on the phone with a rep that had absolutely no technical skills whatsoever. She kept telling me to do things she already watched me do numerous times and at the end told me that I had to file federal taxes before I could do the state. I laughed and said I have been doing TurboTax for 15 years to fall for that. 

I tried on my laptop today and it worked. So as one of the suggestions before took the old 2018 Forms files from the C:\Program Files (x86)\TurboTax\Deluxe 2019\Forms\XXi_18 (XX being your State abbreviation), I copied the C:\Program Files (x86)\TurboTax\Deluxe 2019\Forms\XXi_19 directory from the working machine and placed it in the C:\Program Files (x86)\TurboTax\Deluxe 2019\Forms of the non-working machine. Relaunched TurboTax 2019 and hoooorah...the state finally registered! Not a real solution, but its a workaround if you have another computer to install TurboTax on.
