There is a cell phone APP called IRS2Go.
The IRS issues more than 9 out of 10 refunds in the normal time frame: less than 21 days. However, it’s possible that some tax returns may require further review and could take longer.
IRS representatives can research the status of your return only if:
It's been more than 21 days since you received your e-file acceptance notification,
It's been more than 6 weeks since you mailed your paper return, or
The Where's My Refund? tool directs you to contact us.
You can start checking on the status of your refund within 24 hours after we've received your e-filed return or 4 weeks after you've mailed a paper return. Have your 2020 tax return handy so you can provide your taxpayer identification number, your filing status, and the exact whole dollar amount of your refund shown on your return.
