You didn't say how long it has been since your efiled return was accepted.
In my situation it took about a month for my 2020 return transcript to change from no record of a return to reflect the filing of a return. I realize that's strictly anecdotal, and not everyone's situation will be the same.
You didn't mention anything about the IRS "Where's My Refund" tool. If you are sure your efiled return was accepted (which you can double-check at the Tax Home of your Online account), then what is displayed at the IRS WMR tool?
Tips on using the IRS WMR tool:
You can also try phoning the IRS refund hotline. I've seen it work for some users when the WMR tool didn't. 800-829-1954
