Ok ... did you actually efile successfully ? If you did not the TT program is reminding you to do so now. If you made the payment already directly thru the IRS site so as already mentioned simply choose the mail in check option in the program so you can proceed to efiling.
If you are not sure if you successfully efiled then you can check the IRS online using the Where's My Refund? tool by entering in $1 for the refund when asked ... https://www.irs.gov/refunds
