Here's what I've experienced, in case this timeline helps clarify things for anybody:
Feb. 23 2020: E-filed original 2019 Federal return through TurboTax
Mar. 9 2020: Received refund electronically
May 18 2020: Mailed my amended return along with a check for underpayment
July 31 2020: Check was deposited by the IRS
Oct. 1 2020 or so: The "Where's My Amended Return?" website finally shows some activity. Until this point, there was no information. I can now select a 2019 option and click CONTINUE. When I do do so, I get this:
"Your amended return was received on June 01, 2020. However, it has not been processed. We apologize for any inconvenience. Please call [phone number removed], extension 623, between the hours of 7 a.m. and 7 p.m., Monday through Friday. You will need a copy of your amended return."
November 20, 2020 (today): I called the number and was told the hold would be 10 to 15 minutes. It ended up being 40, but I talked to an agent, and he said that even though the system shows June 1 as the receipt date, it's the date it shows up in the system (he stated the date as October 1) when the 12- to 16-week processing period STARTS. He advised me to periodically check the website for an update. If I don't see an update in January/February, I should call back.
I hope that helps others who are waiting.
