I am having the same difficulties. This issue also plagued me with the 2018 returns. I spent hours upon hours with specialists.
Multiple state returns requried to be filed, preparation of free state works fine. I just purchased 2 additional states. When DOWNLOAD is selected, nothing happens. We end up at the YOUR STATE RETURNS page with START next to the states I've already purchased.
When START is selected, I get brought through the whole purchase a new state process again. I have the abillity to "CHECK THE BOX NEXT TO EACH STATE TO ADD IT TO YOUR RETURN. YOU WONT BE CHARGED FOR THIS."
Select DOWNLOAD NOW and then the same loop happens all over again. Back at YOUR STATE RETURNS with START next to these states I have already paid for, but have NOT downloaded.
