Where's my refund tool not working and IRS not taking phone calls

[ylinab210]

My Federal Return was accepted 26 days ago. I had an estimated refund date of 3/4/2021 but nothing. The IRS is apparently not taking phone calls either due to "high call volume". I've tried calling at different times of the day and it doesn't seem to matter. The find my refund tool says there is no record of my return. I've tried multiple times. I'm certain the information is correct. How am I supposed to know what's going on with my refund??

It can take 21 days from the time your return is accepted to the time you receive your refund.  It may also take longer due to other reasons, such as the particular forms that were filed, or due to the PATH Act.  For more details, please see the Help Article here.
