When I Track my refund it says scheduled to be mailed by February 27th. We chose the direct deposit choice. So does that mean it'll be mailed in a check?

If you chose direct deposit and entered all of your bank information, your refund will be deposited into your account within 3 weeks of the date your return was accepted. It will not be mailed as a check unless you chose that option. It's just a generic statement on the website, no worries.
