Include a statement if you want, but I have not heard of any IRS problems with this. The IRS does not process mailed tax returns, there are clerks that enter mailed returns into the main IRS processing computer for processing and they tend to disregard anything hand written on the tax rerun. But it would not hurt anything to add it.
The 8615 was very late in being released because of those tax law changes, so some things might have been overlooked. If the IRS schema called for that statement then I am sure the TurboTax developers would have adhered to the schema (schemas used to be publicly available but 2 years ago the IRS restricted them to to IRS account holders with a login.) so there is no way to check what was actually specified.
