8453-pe form not supported

I'm trying to e-file my partnership return using Turbo Tax Business. It says I must include form 8453-PE, but when I try to print the form it says "DO NOT FILE. FORM NOT FINAL". According to the Turbo Tax list of forms, this one is not supported. Is it needed to e-file? If so, can I e-file without it and mail it in later? Thanks in advance!
