The IRS created a website where you can check the status of your stimulus check and update direct deposit info.
Link: IRS Where's My Stimulus Link & Payment Update
Once inside click on the "Get My Payment" box
**note that many folks are experiencing difficulties with this website not functioning properly. Unfortunately this is the only avenue we have from the IRS as a tool to check on the status of your stimulus check. If you do not get your stimulus check now, you will get it as part of your 2020 income tax return filing if you meet with qualifications.
