The term "accepted" is only an efile term and has nothing to do with a mailed return. It simply means an efiled return (for those who efiled) was accepted by the IRS in the right format for processing to begin. You don't get any notice like that for a mailed return.

How have you been doing that? Looking where? If you are in your online IRS account looking at a transcript, it can take a long time for a mailed return to show up in the transcript.
And the IRS "Where's My Refund" lookup tool is only for tax years 2021-2023.
You're lucky you got your green receipt card back. It can sit in a bag of mail for a long period of time. Sometimes they don't even bother to send it back. They get so much certified mail that they often just sign a manifest of item numbers prepared by the USPS and later go through the bag.
It can take at least 6-8 weeks or longer to process a mailed paper return.
