I used turbotax deluxe to file 2017 taxes. I just got info the state of Iowa says I owe money to the state for an error. Does turbo tax provide support for this?

TurboTax has a special phone number for help with IRS tax letters, which will be easier than going through regular Customer Support.   At the page below, click on the blue button that says "Get Help from TurboTax Support".  Then it will ask you what tax year is your letter.  Then it will ask you what the letter concerns. Then it will show you the phone number during posted business hours.
