Item 1 and 3, if you want to only file 990 -ext, you will need to check "Form 990Only " in Part II, “File the federal 990,990-EZ... return electronically" and “Electronic Filling of Extensions" on Part VII.

Item 2, ProSeries removed the error message on Form 990T, page 1, item E.

Item 4 and 5, IRS is required to either attach F8453 PDF or use the Practitioner PIN. Form 990 is the only product that has this business rule requirement by the IRS for filing extension.

Thank you for your feedbacks. We are planning to have the enhancements on the information worksheet in the future release to be more user friendly.
