I believe that is talking about the initial reporting of your withdrawal. If you had not reported it last year when you were supposed to you would use 8915-E. Everything I have researched says the form 8915-F should be used to report the 2nd of 3 installments. And as Far as I can tell 8915-F will continue to be used for following years so maybe we won’t have to wait forever with no answers from the IRS.
