Form 1041, estate open for more than 2 years

I am ready to file Form 1041 (for an estate/trust) electronically using Turbo Tax Business. However, I noticed that, Line 8 of the “Other Information” section  states “If the decedent’s estate has been open for more than 2 years, attach an explanation for the delay in closing the estate, and check here”. I am unable to find anywhere in Turbo Tax where an explanation can be entered. Please advise.
