It's been well past 21 days since filing and it's said this for over a week

You might need to call the IRS since it's been more than 21 days.  Please contact https://www.irs.gov/help/telephone-assistance  or IRS.

Please also read this: 

It is also possible that you owed IRS and they took your refund to offset the debt.  I will suggest you contact the Treasury Offset Program at 800-304-3107 to find out.  If this does not apply to you , call the IRS Taxpayer Advocate Service at 1-877-777-4778.  

Here are the possible reasons when the offset is taken:

• Past due child support;
• Debts owed to a federal agency;
• Unemployment debts owed to the state;
• Past due federal student loans;
• Unpaid state income tax.

They did this to me because I claimed the recovery rebate credit. You should call them. If you don't get anywhere with them, you can call TAS.
