AZ revenue dept sent a mail that I owe them taxes for 2021 year. If TurboTax miscalculated my taxes then they will have to take care of it. Is there a phone no to call?

You might want to investigate and see if the letter you received from AZDOR was correct in what they changed on the AZ return causing state income taxes to be owed.

Both the IRS and the States say there was calculation error whenever they change a tax return.
