Get your taxes done using TurboTax

My problem with Form 1116 is that, although it is generated by TurboTax correctly, as far as I can tell, and including Schedule B, I keep getting the following error message when trying to e-file: "We can't efile your return because we are unable to locate the attachment at / attachment/Form1116ScheduleB.pdf. Please go back and re-attach it. Then try efiling again."

Based on advice in another thread, I switched the foreign tax option from credit to deduction (this deleting Form 1116) and then back to credit (necessitating re-entry of all related information), but I get the same error message. I'm using the latest version of TT Home & Business for Windows, version 021.000.559. I was told by customer service that the problem was known and scheduled to be fixed by 3/31, but obviously that has not happened. Any thoughts?
