No IRS tax refund after 20 weeks. It keeps giving me the message that it was received and being processed. What can I do?

Call the IRS: 1-800-829-1040 hours 7 AM - 7 PM local time Monday-Friday
When calling the IRS do NOT choose the first option re: "Refund", or it will send you to an automated phone line.
So after first choosing your language, then do NOT choose Option 1 (refund info). Choose option 2 for "personal income tax" instead.
Then press 1 for "form, tax history, or payment".
Then press 3 "for all other questions."
Then press 2 "for all other questions."
- When it asks you to enter your SSN or EIN to access your account information, don't enter anything.
- After it asks twice, you will get another menu.

Press 2 for personal or individual tax questions.
Then press 4 for all other inquiries
It should then transfer you to an agent.

What tax year did you file 20 weeks ago?    Was it an amended return from a prior year?  It could not be your 2019 return, since the IRS did not begin to accept 2019 returns until January 27, 2020-- less than 10 weeks ago.
