It can take anywhere from a few hours to 3 weeks for the IRS to officially accept your return and then your information should show in the Refund tool within 24 hours of acceptance. The IRS refund tool updates daily so try not to worry. If the status has not changed in the next couple of days then try contacting the IRS.
A suggestion from one of our customers: If you filed your return as head of household, try changing the status in the Refund Tool to single.
