They are not connected. Turbotax uses the IRS estimate of 21 days to give you a refund date. This date will never change because it receives no info about the status of a refund. the actual date is in the hands of the IRS. you do have the option of calling the IRS to find out what might be causing the delay. However, the agent you talk to may not know the reason. I suspect the government shutdown had a significant effect on the issuance of refunds.
