I have Big Sur and started doing my tax return. Then I couldn't get back to my return because Turbotax wouldn't open. I consulted Turbotax a number of times and discarded and reloaded Turbotax twice. It still won't open. If Turbotax can't fix the problem I plan to file a consumer complaint with the Attorney General's office. I suggest you do the same. Turbotax is committing consumer fraud if it can't fix the problem with Big Sur.
