The IRS requires a "manually signed and dated" safe harbor election statement for rental activities. That Rental Real Estate Enterprise Statement is the "safe harbor" statement for your combined (aggregated) rental properties.
Unfortunately, TurboTax does not support a PDF attachment of a signed safe harbor election.
As a result, you are required to print and mail your tax return in order to submit the signed and dated "safe harbor" statement required by the IRS.
