It's not clear if the "processing error" is on the IRS' part or TurboTax', but it seems it's not something I can fix myself. Reject code is F8960-019-04. Any advice on whether to wait or file by mail?
Here's the full "What needs to be done" text: "This return cannot be electronically filed due to a processing error on Form 8960, Net Investment Income Tax. There is currently no estimated date for when this will be resolved. You have two options: 1) You may wait a few weeks and attempt to resubmit this return, or 2) You may print and file the return by mail. This message will be updated when a resolution date is identified."
