E-filing for trust

I e-filed 3 trust return3, but but all were rejected by the IRS. I scanned and upload Form 8453-PE. TT says this form is attached.

After the return was rejected, I reviewed my printed copy of the returns. Form 8453 was not included with the return as filed.

I then review the return I printed for my records that included al the calculations. Form 8453 is included.

Earlier this week, I filed a S-corp and C-corp electronically and Form 8453 was included and both were accepted by the IRS.

I am a CPA and pro-adviser. I have used TT for over 20 years and this is the first time this has happened.

 

Please advice
