There is no such thing.  An amended return has to be printed, signed and mailed.  Amended returns are not "accepted" the way that an e-filed return is accepted.  If you did not mail it, you did not submit an amended return.

A 1040X cannot be e-filed.  It must be printed and mailed.  It will take about 3-4 months for the IRS to process an amended return.  It is a good idea to use a mailing service that will track it, like UPS or certified mail, so you will know it was received.

Wait about 3 weeks from mailing and you can check the status of your amended return:

An amended federal tax return, Form 1040X, can only be printed, signed, dated and mailed by you to the IRS, it can Never be e-filed.  Once the IRS receives the mailed amended tax return the status of the amended return will be available on the IRS website for amended returns here - https://www.irs.gov/filing/wheres-my-amended-return

If you did not print and mail the amended return, then nothing was sent to the IRS.  Unless you are referring to changing your original tax return after it was rejected and then e-filing the tax return.  Then you would have received an email message from TurboTax for the status of the tax return being either Accepted or Rejected.

Or you e-filed the original tax return and it was accepted by the IRS, then you changed the original tax return that was filed and tried to e-file again.  The e-file would be rejected since the original tax return had already been accepted by the IRS.  So only the original return was sent and Nothing you changed on the return has been delivered to the IRS.

Use this TurboTax website to check the status of an e-filed return and if it was either accepted or rejected - https://turbotax.intuit.com/tax-tools/efile-status-lookup/
If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds

I don't know what you mean "accepted".  Amended returns (1040X) can ONLY be printed and mailed.  Amended returns CANNOT ever be e-filed and amended returns do not "accept", they are simply received by the IRS and entered into their system.

If you e-filed it then is was NOT an amended return and if it accepted then that means that it was an original return - not an amended return.
