It says my estimated refund should be received today but I haven’t received it

TurboTax gets no information about the status of refunds. The estimate provided by TurboTax when you file your return was based on a 21 day time frame that is typical for most federal refunds. You can determine the status of your refund using this link: https://www.irs.gov/refunds

if that was a Turbotax message ignore it. It's based on 21 days. some refunds take longer.
