CLEAR AND START OVER
Did you get a 1099Misc for something?
You can try to downgrade to a lower version but you will have to clear and start over.
Or one thing you can do is buy a lower version of the Desktop program like Deluxe. Then you can switch from Online without starting over. You can download the .tax2019 file from online for free and open it in the Desktop program (any version). And the Desktop program has several other features and benefits over the Online version too.
