SAME issue here. Been trying to submit my federal and two state returns (IL and WI) all day/afternoon. Going on hour 6 of just trying to submit. Been hung up on by support 3x and finally got someone who stuck with me for an hour plus of problem solving, however she didn't seem to understand the difference between the mac app and the web based app and kept asking me to try another browser. So.... how do I get to e-file after paying all this money for the program, the extra state download, and the two state filing fees? Nothing is working. I am on a Macbook Air (OS 10.14.6). This is the first year TurboTax has been so useless.
