Patricia,
This is absolutely insane! That form 8453-PE is the signature for the return.
It is absolutely required by the IRS otherwise the tax return is not valid. Whoever on your team is telling you that this form is not required is with all due respect is absolutely incorrect. That form has been part of every business return for turbo tax for at least the last 10 years. That is your signature for your tax return. I don't believe you are getting correct information on this. Turbo tax literally has you go through printing and signing the 8453-PE form then uploading it prior to e-filing the return. You absolutely cannot e-file and expect the IRS to not reject your return. That is like mailing in a return without signing the return.
As a reference, you can take a look at your past business returns filed via Turbo Tax and see that that form is part of every business 1065 return. No return is valid unless the return is signed and the 8453-PE is that signature form if you look at the form. So instructing people to delete the signature form is incorrect. PLEASE FIX THE ISSUE AS THIS IS A HUGE PROBLEM.
