If your question is whether or not the form 4868 that you e-filed was accepted by the IRS, you would have received an email from TurboTax when the e-filed extension request was either Accepted or Rejected by the IRS.
Look in your email account for the TurboTax post, check the account spam or junk mail folders if nothing is shown in your account.
I'm not sure what you mean by "confirmation details." The IRS does not send any confirmation of an extension. They will only contact you if your extension is rejected.
If you e-filed your extension with TurboTax Easy Extension you got an email from TurboTax when your extension was accepted.
A Tax Account Transcript from the IRS (not a Tax Return Transcript) will show that an extension was filed. To get a Tax Account Transcript, go to Get your tax records and transcripts on the IRS web site.
