I believe you are referring to the form 8453-PE.
This was my first time using TT Business. For this year, on my partnership return, I asked why I could not find my signed copy of the Form 8453-PE. Someone responded correctly that after the signed copy of Form 8453-PE is uploaded into TT Business to provide a signed document to TT, not the IRS. TT will acknowledge that the signed form is now attached and accepted. The signed 8453-PE does, in fact, get attached to your return BUT the list of forms, preview, etc. will NOT show the signed form; the signed form should be saved somewhere on your computer where you saved it to upload to TT.
I permitted access to a TT Agent so she could see what I had an issue on. She looked at the form and confirmed that, in her experience, once the form is attached and accepted by TT, the signed form is not shown on either the preview or the saved pdf.
I e-filed my partnership and received an email a few minutes later that the transmission was successful. The email stated it will take 1 or 2 days for the government to process and accept your returns (longer for some states). I received an email 32 minutes later that my 2023 Federal Partnership filing was accepted by the IRS.
I recommended to the TT Agent that TT needs to add a note that, once the form is accepted by TT, the signed form will not be shown on either the preview or the saved pdf. It would certainly save a lot of wasted time for people looking for the signed form 8453-PE in TT Business.
