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:

• Be sure you have waited at least 24 hours after acceptance before using the IRS WMR tool.
• Be sure you enter the correct SSN and filing status.
• Be sure you are using only the Federal refund amount.   Do not include any state refund or any total refund or net refund (Fed and State) that TurboTax may have provided on a screen.  
• Look at your actual Federal return to get the Federal refund amount, i.e., your Form 1040, Line 35a.

• 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

Until the return is PROCESSED it will not show up on the transcript site and sometimes even longer than that since the IRS is short staffed again this year and everything is taking much longer to be completed.
