I filed on 2/17, never got the email 24-48 hours later (not even in spam/junk), but logged in to TurboTax to see the return was “accepted”. It has been in that state for a full month now (today is 3/18) and Where’s My Refund tool still says there’s no record of our refund. The “expected refund date” was 3/10.
The IRS "Where's My Refund" tool has been quirky this year.
You may want to try the IRS Refund Hotline, too. I've seen it work for some users when the WMR tool didn't. 800-829-1954
TIPS when using the IRS "Where's My Refund" tool:
Since your return has been accepted more than 21 days, you can phone the IRS, if you wish, to see if they can tell you what is going on with your return. Here's how to normally reach a live IRS agent, but these are not normal times, so it won't be easy.
IRS: 800-829-1040 (7AM-7 PM local time) Monday-Friday
When calling the IRS do not choose the first choice re: "Refund", or it will send you to an automated phone line.
