I filed return using e-file. I realised after filing that I missed one 1099-R form so I amended my return within 30min. Do I need to mail the amended return?

how do I know if my amended return will also get e-filed?

If you have not filed the amended return, you should wait.  

• Allow the IRS to completely process the original return.  
• They may detect the missing 1099-R and send you a request for additional information.
• Once your original return is accepted and processed you can file the amendment if you need to.

Thanks for the reply.
I actually amended the return on turbo tax desktop app within 30 min.
Now I have two local .dat files and  when I open both of them one by one then both show in "Check e-file status" as Accepted.
Does it mean both my original and amended returns have been accepted by IRS.

[DaveF1006]

Yes, you are correct. Both are accepted.

Thanks Dave.
Is there a way to check what IRS has got as my tax documents?

[SharonD007]

Accepted means that the IRS received your tax return and has passed initial screening.  It doesn’t mean that it was processed or approved.

Refer to the IRS website Refunds for more information about your IRS refund. Refer to the TurboTax article What does Accepted mean?

I am more interested in knowing the details of tax information that they have received like 1099-R forms
