But you can fully expect the ability to e-file the 2019 form 1065 (amended or not) to be TURNED OFF completely and forever on Sept 15th by the IRS - not by TurboTax.
Carl, it is TurboTax that turns that off. The IRS e-file system for business returns (such as Form 1065) is usually open until December, then opens back up in mid-January (and accepts the 2 previous year's of tax returns).
