Once you have successfully efiled the return there is nothing you can do in the program to change it ... what you may have done is opened the account by clicking on the amendment process which does nothing but change the Refund-O-Meter to zero ... save a PDF of the return using the PRINT CENTER  to see what you actually filed ...

and also check the IRS site to see where you are in the process :   www.IRS.gov/refunds

Your federal refund is the amount shown on line 20 of your original form 1040.

TurboTax gets no information about the status of your refund.
In normal times, the IRS says that most filers get their refunds within 21 days from the time their tax return is accepted. Some refunds take longer.
Many returns are taking longer now since the IRS did not process returns for a while and there is now a big backlog of unprocessed returns. The IRS is currently not processing any mailed returns. 

If you efiled your return, have you confirmed that the return was submitted and accepted by the IRS?
